Question

by selling an article for rupees 1470 a man gain 1/5 of its cost price . find its gain percent? How

Answer 1

Hi ,

Let the cost price ( c.p ) = Rs x

Gain = c.p / 5

= x / 5

c.p + gain = s.p

x+ x/5 = 1470

( 5x + x ) / 5 = 1470

6x /5 = 1470

x = ( 1470 × 5 ) / 6

x = 245 × 5

x = 1225

Therefore ,

C.p = x =Rs 1225

gain = x/5

g = 1225/5

g = Rs245

Gain % = ( g × 100 ) / CP

= ( 245 × 100 ) / 1225

= 100/5

= 20%

I hope this helps you.
