A and B together have Rs. 1210. If $\frac { 4 } { 15 }$ of A's amount is equal to $\frac { 2 } { 5 }$ of B's amount, how much amount does B have?

Rs. 460

Rs. 484

Rs. 550

Rs. 664

Answer : Option B

Explanation :

$\frac { 4 } { 15 }$ A = $\frac { 2 } { 5 }$ B

A =[ $\frac { 2 } { 5 }$ x $\frac { 15 } { 4}$ ]B

A = $\frac {3 } { 2}$ B

$\frac {A } { B}$ = $\frac {3 } { 2}$

A : B = 3 : 2

B's share = Rs[1210 x $\frac { 2 } { 5 }$ ] = Rs. 484
