7.2; Let the smallest no. be x ,
so, 4 + 8 + 1 + x + 6 + 7 + 3 should be divisible by 9
==> 29 + x, should be divisible by 9
==> if x = 7, 29 + 7 = 36, divisible by 9.

8.4; Number = 56 x + 29
==>Let x = 1, then number = 56 × 1 + 29 = 85
==>85 ÷ 8 = 10, remainder = 5.

9.3; Let x and (12 - x) be litres of milk from 1st and 2nd
container :- Amount of milk (x litres) of 1st container = 0.70 x
==> Amount of water = 0.3 x
==> Amount of milk (12 - x) in 2nd
container = 0.5 (12 - x)
==> Amount of water = 0.5 (12 - x)
==> Ratio of water to milk =

==> Solving x = 7.5,  12 -x = 4.5

 

10.1; 4 weeks = 4 × 6 × 10 = 240 hours.
regular = 240 ×2.10 =  `  504
Total = 525 - 504 = 21
21/2.4 = 5 hours, so total = 240 + 5 = 245 hours
