Answer 1

Answer:

(i) Total amount of money = ₹3450

Ratio of money between A, B and C = 3:5:7

Sum of ratios = 3+5+7 = 15

A's share =

$\frac{3}{15} \times 3450 = 690$

B's share =

$\frac{5}{15} \times 3450 = 1150$

C's share =

$\frac{7}{15} \times 3450 = 1610$

(ii) Number of boys in school = 480

Number of girls in school = 384

Ratio of no. of boys to no. of girls =

480 : 384 = 5 : 4

Answer 2

1. let A = 3x

let B = 5x

let C = 7x

therefore ,

$3x + 5x + 7x = 3450 \\ 15x = 3450 \\ x = \frac{3450}{15} \\ x = 230$

$ratio \: = \frac{number \: of \: girls \: }{number \: of \: boys} \\ = \frac{384}{480} = \frac{24}{30} = \frac{4}{5}$

therefore ,

A = 3 × 230 = ₹690

B = 5 × 230 = ₹1150

C = 7 × 230 = ₹1610

2. number of boys = 480

number of girls = 384

therefore ,
