Question

Divide rs.940 among a,b,c in the ratio 1/3:1/4:1/5

Answer 1

Ratio = 1/3:1/4:1/5 = 60/3 : 60/4 : 60/5 = 20:15:12

a's share = 20/20+15+12 x 940 /- = 20/47 x 940 /- = 400 /-

b's share = 15/47 x 940 /- = 300/-

c's share = 12/47 x 940 /- = 240/-

Answer 2

Step-by-step explanation:

given

total money =940

let the ratio of a b c be X

so,

part of A=1/3x

part of B=1/4x

part of C=1/5

thus

sum of their money =940

$= > \frac{1}{3} x + \frac{1}{4} x + \frac{1}{5}x = 940 \\ \\ = > \frac{20x + 15x + 12x}{60} = 940 \\ \\ = > \frac{47x}{60} = \frac{940}{1} \\ \\ = > 47x = 940 \times 60 \\ \\ = > x = \frac{940 \times 60}{47} \\ \\ = > x = 20 \times 60 = 1200 \\ hence \: \\ part \: of \: a = \frac{1}{3} \times 1200 = 400 \\ \\ part \: of \: b = \frac{1}{4} \times 1200 = 300 \\ \\ part \: of \: c = \frac{1}{5} \times 1200 = 240$
