Solution :-

1.

a) 85400, 7861, 7500, 5000

b) 92547, 88715, 45321, 1971

2.

a) 73,75,317

b) 9,05,00,041

3.

a) Eight crore seventy five lakh ninety five thousand seven hundred sixty two (8,75,95,762)

b) Eighty five lakh forty six thousand two hundred eighty three (85,46,283)

4.

a) Seventy eight million nine hundred twenty one thousand ninety two (78,921,092)

b) Seven million forty hundred fifty two thousand two hundred eighty three (7,452,283)

5.

Given :-

No. of medicine tablets = 2,00,000

Weight of each one tablet = 20 mg

Weight of total no.s of tablets

= 2,00,000 × 20 mg

= 20,00,000 mg

Converting mg into g

1000 mg = 1 g

2000000 mg = 2000000 ÷ 1000 g

= 2000 g

Converting g into kg

1000 g = 1 kg

2000 g = 2000 ÷ 1000 kg

= 2 kg

6.

No. of population in 199 1 = 2,35,471

No. of popution increased in 2001 = 72,958

So, Total no. of population after increasing

= 2,35,471 + 72,958

= 3,08,429

7.

No. of pages one copy printed = 12 pages

Total no. of copy printed = 11,980 copy

Therefore,

Total no. of pages printed in total copy

= 11,980 × 12 pages

= 1,43,760 pages.
