Answer 1

$\huge\mathfrak\pink{Answer}$

Let the C.P. of the 1 st

scooter = Rs. x.

Then, C.P. of the 2 nd

scooter = Rs. (18000−x)

S.P. of 1 st

scooter = Rs. x× 100125 = Rs. 45x

S.P. of 2 ndscooter = Rs. (18000−x)× 10080

= Rs. 54(18000−x)

Since Mohan neither gains nor loses, his total S.P. = Total C.P.

⇒ 45x + 54 (18000−x)=18000

⇒ 45x − 54x

=18000−14400=3600

⇒ 2025x−16x

=3600⇒9x=3600×20

⇒x= 93600×20 =8000

∴ C.P. of 1 st scooter = Rs. 8000C.P. of 2 ndscooter = Rs. 10,000.
