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?

Answer 1

Answer:

b will have rs 484

Step-by-step explanation:

Total=1210

a=4x/15

b=2y/5

x+y=1210.....!

4x/15=2y/5......!!

20x=30y......!!

x=30y/20.....!!

30y/20+20y/20=1210

hence y=484

b=484

Answer 2

$\huge{\underline{\underline{\huge{\bold{AnsweR \: :-}}}}}$

Rs.484

$\huge{\underline{\underline{\huge{\bold{Solution \: :-}}}}}$

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

$\large\sf{⇒ A = (\frac{2}{5}×\frac{15}{4})\:B}$

$\large\sf{⇒ A = \frac{3}{2}\: B}$

$\large\sf{⇒} \frac{A}{B}=\frac{3}{2}$

$\large\sf{⇒ A:B= 3:2}$

$\large\sf\color{red}{∴B's \:Share = Rs.(1210×\frac{2}{5})= Rs.484}$
