Answer – D. 10%

Answer – A. 45

Explanation:

Given that

Total ages of 30 boys = 14 x 30 = 420 years

Let us assume initially income is 100.

So, expenditure = 60 and saving = 40

Now income is increased by 20% that is 120.

So, expenditure = (70/100)*120 = 84 and saving = 36

so % percent decrease in saving = (4/40)*100 = 10%

Explanation:

5m + 10b = 1/30 and 8m + 12b = 1/20

0.7 = 100x-3355/3135-100x

2194.5 – 70x = 100x-3355

170x = 5549.5
