Q.3 Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation.

(a) 5m=60(10,5,12,15)(b) n+12=20(12,8,20,0)(c)p−5=5(0,10,5,−5)(d)q2=7(7,2,10,14)(e)r−4=0(4,−4,8,0)(f)x+4=2(−2,0,2,4)

Ans.

(a) We have, 5m =60 …(i) Putting m = 10 in L.H.S. of equation (i), we get5m = 5(10) = 50≠60⇒     L.H.S.≠R.H.S.So, m=10 is not the solution of equation 5m =60.Again,Putting m=5 in L.H.S. of equation (i), we get5m= 5(5)= 25≠60⇒L.H.S.≠R.H.S.So, m=5 is not the solution of equation 5m=60.Again, Putting m=12 in L.H.S. of equation (i), we get 5m= 5(12)=60⇒    L.H.S.=R.H.S.So, m=12 is the solution of equation 5m=60.Again,Putting m=12 in L.H.S. of equation (i), we get 5m= 5(12) = 60⇒    L.H.S.=R.H.S.So, m=12 is the solution of equation 5m=60.Again,Putting m=15 in L.H.S. of equation (i), we get 5m= 5(15) = 75⇒    L.H.S.≠R.H.S.So, m=15 is not the solution of equation 5m=60.(b) We have, n+12=20 …(i) Putting n=12 in L.H.S. of equation (i), we get   n+12=12+12 =24≠20⇒     L.H.S.≠R.H.S.So, n=12 is not the solution of equation n+12=20.Again,Putting n=8 in L.H.S. of equation (i), we get   n+12=8+12 =20⇒   L.H.S.=R.H.S.So, n=8 is the solution of equation n+12=20.Again,Putting n=20 in L.H.S. of equation (i), we get   n+12=20+12 =32≠20⇒   L.H.S.≠R.H.S.So, n=20 is not the solution of equation n+12=20.Again,Putting n=0 in L.H.S. of equation (i), we get   n+12=0+12 =12≠20⇒      L.H.S.≠R.H.S.So, n=0 is not the solution of equation n+12=20.(c) We have, p−5=5 …(i) Putting p=0 in L.H.S. of equation (i), we get     p−5=0−5 =−5≠5⇒     L.H.S.≠R.H.S.So, p=0 is not the solution of equation p−5=5.Again,Putting p=10 in L.H.S. of equation (i), we get    p−5=10−5 =5⇒   L.H.S.=R.H.S.So, p=10 is the solution of equation p−5=5.Again,Putting p=5 in L.H.S. of equation (i), we get    p−5=5−5 =0≠5⇒   L.H.S.≠R.H.S.So, p=5 is not the solution of equation p−5=5.Again,Putting p=− 5 in L.H.S. of equation (i), we get    p−5=−5−5 =−10≠5⇒   L.H.S.≠R.H.S.So, p=− 5 is not the solution of equation p−5=5.(d) We have, q2=7 …(i) Putting q=7 in L.H.S. of equation (i), we get            q2= 72 =3.5≠7⇒   L.H.S.≠R.H.S.So, q=7 is not the solution of equation q2=7.Again,Putting q=2 in L.H.S. of equation (i), we get            q2= 22 =1≠7⇒   L.H.S.≠R.H.S.So, q=2 is not the solution of equation q2=7.Again,Putting q=10 in L.H.S. of equation (i), we get            q2= 102 =5≠7⇒   L.H.S.≠R.H.S.So, q=10 is not the solution of equation q2=7.Again,Putting q=14 in L.H.S. of equation (i), we get            q2= 142 =7⇒   L.H.S.=R.H.S.So, q=14 is the solution of equation q2=7.(e) We have, r−4=0 …(i) Putting r=4 in L.H.S. of equation (i), we get     r−4=4−4 =0⇒   L.H.S.=R.H.S.So, r=4 is the solution of equation r−4=0.Again,Putting r=− 4 in L.H.S. of equation (i), we get     r−4=− 4−4 =− 8≠0⇒   L.H.S.≠R.H.S.So, r=− 4 is not the solution of equation r−4=0.Again,Putting r=8 in L.H.S. of equation (i), we get     r−4=8−4 =4≠0⇒   L.H.S.≠R.H.S.So, r=8 is not the solution of equation r−4=0.Again,Putting r=0 in L.H.S. of equation (i), we get     r−4=0−4 =− 4≠0⇒   L.H.S.≠R.H.S.         So, r=0 is not the solution of equation r−4=0.(f) We have, x+4=2 …(i)          Putting x=− 2 in L.H.S. of equation (i), we get    x+4=− 2+4 =2⇒   L.H.S.=R.H.S.       So, x=− 2 is the solution of equation x+4=  2.Again,         Putting x=0 in L.H.S. of equation (i), we get    x+4=0+4 =4≠2⇒   L.H.S.≠R.H.S.        So, x=0 is not the solution of equation x+4=  2.Again,         Putting x=2 in L.H.S. of equation (i), we get    x+4=2+4 =6≠2⇒   L.H.S.≠R.H.S.         So, x=2 is not the solution of equation x+4=  2.Again,         Putting x=4 in L.H.S. of equation (i), we get    x+4=4+4 =8≠2⇒   L.H.S.≠R.H.S.So, x=4 is not the solution of equation x+4=  2.

By inspection of the table, the solution to the equation z/3 = 4 is z = 12.

(d) Table having solution of m – 7 = 3, is given below:

m m-7
5 5 – 7 = – 2
6 6 – 7 = – 1
7 7 – 7 = 0
8 8 – 7 = 1
9 9 – 7 = 2
10 10 – 7 = 3
11 11 – 7 = 4
12 12 – 7 = 5
13 13 – 7 = 6

By inspection of the table, the solution to the equation m – 7 = 3 is m = 10.

Q.5 Solve the following riddles, you may yourself construct such riddles. Who am I?
(i) Go round a square
Counting every corner
Thrice and no more!
Add the count to me
To get exactly thirty four!

(ii) For each day of the week
Make an upcount from me
If you make no mistake
You will get twenty three!

(iii) I am a special number
Take away from me a six!
A whole cricket team
You will still be able to fix!

(iv) Tell me who I am
I shall give a pretty clue!
You will get me back
If you take me out of twenty two!

Ans.

(i) Let value of me be x.
Number of corners in a square = 4
Thrice of 4 = 12
Then, x + 12 = 24
x = 24 – 12
= 22
Therefore, the value of me is 22.

(ii) Let value of me be x.
Upcount on Sunday from me = x + 1
Upcount on Monday from me = x + 2
Upcount on Tuesday from me = x + 3
Upcount on Wednesday from me = x + 4
Upcount on Thursday from me = x + 5
Upcount on Friday from me = x + 6
Upcount on Saturday from me = x + 7
In this way, x + 7 = 23
x = 16
Therefore, the value of me is 16.

(iii) Let the special number be x
Number of player in cricket team
= 11
Subtracted number = 6
Then, according to condition,
x – 6 = 11

(iv) Let the value of me be x.
Then, according to condition,
22 – x = x
22 = 2x
x = 11
Therefore, the special number is 11.
