_____________________________
C.P. of goods = ₹ 840
Profit % = 20 %
S.P. of goods = ?

S.P. of goods = ₹ 1008
___________________________
C.P. of 1/4 of goods = 1/4 × 840
=> ₹ 210
Loss % = 20 %
S.P. of 1/4 of good = ?

S.P. of 1/4 of goods = ₹ 168
Remaining goods = 1 - 1/4 = 3/4 of goods
S.P. of remaining goods = 3/4 × 1008
=> ₹ 756
C.P. of remaining goods = 3/4 × 840
=> ₹ 630
Gain = ₹ 756 - ₹ 630 = ₹ 126
Gain % = ?

Answer:
Step-by-step explanation: if 1/4th items have been sold at a loss of 10%
Then 1×-10 = -10
Remaining 3 items must be sold to get 50% profit so that avg profit would be 10 %
So 3 × Y = 50
So Y would be 16.67%
