Question

1. Find the gain or loss per cent when:
(i) CP = 620 and SP = 713
​

Answer 1

CP= 620, SP=713
As SP>CP, So person got Profit.
Profit/gain= SP-CP
= 713-620
= 93
Gain percent= (gain/CP)*100
= (93/620)*100
= (0.15)*100
= 15%

Answer 2

✥ Given that,

CP = 620

SP = 713

★ We know that,

SP is more than CP so it’s a gain. As the formula states Gain = SP – CP

= 713 – 620

= 93

Gain% = (Gain × 100) / CP

= (93 × 100) / 620

= 15%
