Answer:
SP= ₹750
Loss= 10%
CP = 100/100-L% ×SP
= 100/100-10 ×750
= 100/90 ×750
= ₹833.34
Gain= 5%
SP= 100+G%/100 ×CP
= 100+5/100 ×833
=105/100×833
= ₹875
Answer:
Selling price = 765
loss% = 10%
cost price
s.p = (1-loss%) of x
765 = 90/100 of x
850
For finding the s.p, we will use the formula,
s.p = (1+profit%) of c.p
= 110/100 × 850
935
thus the selling price is 935.
