Listen @Yogesh.

Take A=3x and B=2x.
5x= 1210 => x= 242.
Then B= 2 * 242= 484 Ans.

A4/15 = B2/5.
A/B = 3/2,
5 = 1210,
1 = 242,
B = 242 of 2 = 484.

A+B=1210

(4/15)A=(2/5)B

2A=3B

Therefore, A=(3B)/2

and substituting, (3B/2)+B=1210

and hence, 5B=2420 => B=484 Rs.

Nothing ya. just simple.

4/15=2/5

How it will bcom equal ? just c the denominator.
4/15
If you multiply 5 by 3 u will get 15 do it in the numerator also so it becoms 6/15 for B. calculate ratio for B now 1210*6/15= 484

solution.
4/15 = 2/5
4/15 = 2/5*3/3
4/15 = 6/15
therefor A:B 4:6
1210 * 6 / 15
484
