Question

divide rate 6240 among A B and C in such a way that their shares are in the ratio 1/2 : 1/3 : 1/4​

Answer 1

Step-by-step explanation:

Given, 21A=31B=61C

Let 21A=31B=61C=k

∴A=2k, B=3k, C=6k

i.e. A,B and C have amounts in the ratio

A:B:C=2:3:6

Now, 2+3+6=11

Hence, A's part =112 of the total amount.

B's part =113 of the total amount.

C's part =116 of the total amount.

We want to find the B's part.

Also, the total amount is Rs. 3960.

∴B's  part =113×3960=1080

Answer 2

I/2 :3:1/4

let the proportionality be x.

x/2:3x:x/4

if we add them, then the sum will be 6240

so,

x/2 + 3x + x/4 = 6240

by taking LCM

(2x +12x+x) /4

15x / 4 = 6240

15x = 6240 x 4

15x = 24960

x= 1664

x/2 = 832

3x = 4992

x/4 = 416

hence, divided
