Percentage Practice Test 1 with solutions

Total number of girls = 14% of 350 $=\frac{14}{100}\times 350=49$
∴ No. of boys = 350 - 49 = 301
Monthly fee of each girl Rs 520
∴ Monthly fee of each boy 125% of 520 $=\frac{125}{100}\times 520$ = Rs. 650
Hence, 20% of the total monthly fee of boys and girls together
= 20% of [(49 × 520) + (301 × 650)]
$=\frac{20}{100}\times \left[25480+195650\right]$ = Rs 44,226
