Total Distance travelled by the student from school to home and from home to school is = 2 x 1875 = 3750 m

Distance travelled by the student in six days is = 3750 m x 6 – 22500 m = 22 km 500 m.

Therefore, the total distance covered in 6 days = 22 km 500 m.

Question 36.

A merchant had ₹78,592 with her. She placed an order to purchase 40 radio sets at ₹1200 each. How much total money will remain with her after the purchase?

Amount of money present with the merchant = ₹78,592

Total Number of the radio sets = 40

Price of one of the radio set = ₹1200

Therefore, the cost of 40 radio sets = ₹1200 x 40 = ₹48,000

Remaining money left with the merchant = ₹78,592 – ₹48000 = ₹30,592

Hence, the amount of ₹30,592 will remain with her after purchasing the following radio sets.

Question 37.

A vessel has four litres and 500 ml of curd. How many total glasses, each of 25 mL capacity, can be filled?

(i) 730 + 998

Rounding off 730 nearest to hundreds = 700

Rounding off 998 nearest to hundreds = 1,000

∴ 730 + 998 = 700 + 1000 = 1700

(ii) 796 – 314

Rounding off 796 nearest to hundreds = 800

Rounding off 314 nearest to hundreds = 300

∴ 796 – 314 = 800 – 300 = 500

(iii) 12,904 + 2,888

Rounding off 12,904 nearest to thousands = 13000

Rounding off 2888 nearest to thousands = 3000

∴ 12,904 + 2,888 = 13000 + 3000 = 16000

(iv) 28,292 – 21,496

Rounding off 28,292 nearest to thousands = 28,000

Rounding off 21,496 nearest to thousands = 21,000

∴ 28,292 – 21,496 = 28,000 – 21,000 = 7,000
