Solution

₹ 176.40

Explanation;

Hint:

Cost price of article = ₹ 150

Overhead expenses = 12% of cost price

= `12/100 xx 150`

= ₹ 18

∴ Effective cost of article = 150 + 18 = ₹ 168

Now, to gain 5%, he has to sell at

S.P = `"C.P" xx ((100 + "gain"%)/100)`

= `168 xx (((100 + 5))/100)`

= 168 × 1.05

= 176.40
