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 = 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.

(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

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
