A shop keeper purchased 15 kg of sugar and 20 kg of wheat at Rs. 50 and Rs. 75 per kg respectively. On selling them, he gained 10% on sugar and 20% on wheat. What was the total sale value?
C.P of 15 kg sugar = $$15\times\ 50=750$$
S.P of sugar at 10% gain = $$750\times\ \frac{110}{100}=825$$
C.P of 20 kg sugar = $$15\times\ 75=1500$$
S.P of sugar at 20% gain = $$1500\times\ \frac{120}{100}=1800$$
Total sale value = 825+1800 = Rs 2625.
