1.	If the selling price of a TV set is equal to 6/5 of its cost price, find the gain per cent.
Answer» Let × be the CP of TV Set CP = x SP = (x) × 6/5 = 6x/5 Gain = SP – CP = 6x/5 – x = x/5 \(Gain\%=\frac{Gain\times100}{CP}\) = (x/5 × 100) / x = 20% So, If TV set is sold at 6/5 price of its CP. Then Gain percent will be 20%.

If the selling price of a TV set is equal to 6/5 of its cost price, find the gain per cent.

Answer»

Let × be the CP of TV Set

CP = x

SP = (x) × 6/5

= 6x/5

Gain = SP – CP

= 6x/5 – x

= x/5

\(Gain\%=\frac{Gain\times100}{CP}\)

= (x/5 × 100) / x

= 20%

So, If TV set is sold at 6/5 price of its CP. Then Gain percent will be 20%.
