Question

If one third of a number exceeds one fifth of it by
42, find the number
(1) 325
(2) 345
(3) 305
(4) 315​

Answer 1

Answer:

(4) 315

Step-by-step explanation:

let number be A

From question $\frac{A}{3}$ = $\frac{A}{5}$ + 42

$\frac{A}{3}$ $- \frac{A}{5}$ =  42

$\frac{A(5-3)}{15}$  =  42

$\frac{A2}{15}$  =  42

$\frac{A}{15}$  =  21

A  = 15x21

A = 315 ans
