Question

A and b together have rs. 1210. if 4/15 of a's amount is equal to 2/5 of b's amount, how much amount does b have?
a.rs. 460
b.rs. 484
c.rs. 550
d.rs. 664

Answer 1

let a'amount be x
therefore, b's amount be 1210-x
4/15*x=2/5*(1210-x)
4*x*5=2*15*(1210-x)
20x=30(1210-x)
20x=36300-30x
50x=36300
x=726 rs
b=1210-x
  =1210-726=484 rs
therefore ,
the answer is (b)
