Study the following table and answer questions: Number of students studying in five schools of a city Schools No of Students  Ratio of boys and  girls Boys : Girls A 680 9 : 08 B 720 4 : 05 C 540 5 : 13 D 660 2 : 01 E 900 13 : 12 The total number of girls in schools B and C is what percent less than the total number of boys in schools A and D? Correct Answer 1.25

GIVEN:

Number of Schools = 5

CALCULATION:

Total Number of Girls in B and C = 720 × (5/9) + 540 × (13/18)

                                                     = 400 + 390 = 790

Total Number of Boys in A and D = 680 × (9/17) + 660 × (2/3)

                                                     = 360 + 440 = 800

Required Percentage = (800 - 790) × 100/800

Required Percentage = 1.25%
