Answer: Moped Price = ₹ 5,250  

Explanation:
Given data: Scooter price : Moped price = 9 : 5                   eqn. 1
Let scooter prize is ‘S’ and moped prize is ‘M’.

So; S = M + 4200                              eqn. 2

According to eqn. 1 and eqn. 2

S / M = 9 / 5
(M + 4200) / M = 9 / 5
1 + 4200/M = 9/5
4200/M = 9/5 – 1 = 4/5

4200 * 5 = 4 * M
21000 = 4 * M
5250 = M

Price of Moped = ₹ 5,250  
Price of Scooter = ₹ 9,450
