Rahul wants to sell a watch at a profit of 20%. He bought it for 10% less and sold it at Rs. 30 less, but still, he gained 20%. The cost price of the watch ?
Answer & explanation
Correct answer: option 1
C.P. : Profit % : S.P
1st : 100 : 20 : 120
2nd : 90 : 20 : 108
Here,
⇒ Difference b/w SP1 and SP2 = 12R
⇒ 12R = 30 (given)
⇒ 1R = 2.5
⇒ Initial C.P. = 100R = 100 × 2.5 = 250
