A person wanted to sell a scooter at a loss of 25%. But at the last moment he changed his mind and sold the scooter at a loss of 20%. If the difference in the two SP’s is ₹ 4000, then find the CP of the scooter.
उत्तर
Let the cost price of the scooter be ₹ x
If he sells the scooter at a loss of 25%, then
SP = x – 25% of x = `x - 25/100x` = ₹ `75/100x`
and if he sells the scooter at a loss of 20%, then
SP = x – 20% of x = `x - 20/100x` = ₹ `80/100x`
It is given that the difference in the two SP's is ₹ 4000
∴ `80/100x - 75/100x` = 4000
⇒ `(80x - 75x)/100` = 4000
⇒ `(5x)/100` = 4000
⇒ x = `(4000 xx 100)/5` = ₹ 80000
Hence, cost price of scooter is ₹ 80000.
