10. Manu spent 50 rupees for lunch and 24 rupees for breakfast everyday. How much money do Manu spend in 5 days on these things?

1. Zero

2. 600

3. One

4.94

5. a) Successor of 2000 is 2001
Predecessor of 2000 is 1999.
b) Successor of 999 is 1000
Predecessor of 999 is 998.

6. (237 + 343) + (102 + 548) = 580 + 650 = 1230

7. a) 5432 x (2 x 50) = 5432 x 100 = 543200 (by associative property)
b) 765 x (125 x8) = 765 x 1000 = 765000

8. a) 654 x(47 + 53) (by distributivity of multiplication over addition)
= 654 x 100 = 65400
b) 7896 x (146 -46) (by distributivity of multiplication over subtraction)
= 7896 x 100 = 789600

9. a) 654 x (100 + 2) = 654 x 100 + 654 x 2 = 65400 + 1308 = 66708
b) 124 x (1000+ 5) = 124 x 1000 + 124 x 5 = 124000 + 620 = 124620

10. Money spent for lunch = Rs 50

Money spent for breakfast = Rs 24
Money spent in one day = 50 + 24 = Rs 74
Money spent in 5 days = 74 x 5 = Rs 370
