Answer 1

❥︎ANSWER

Let cost of scooter = 9x

Let cost of scooter = 9xand Let cost of cycle = 5x

Let cost of scooter = 9xand Let cost of cycle = 5xWe have, 9x - 5x = 4,200

Let cost of scooter = 9xand Let cost of cycle = 5xWe have, 9x - 5x = 4,200x = 1,050

Let cost of scooter = 9xand Let cost of cycle = 5xWe have, 9x - 5x = 4,200x = 1,050∴ cost price of cycle = 5 × 1,050 = Rs. 5,250

I hope it will help you.

Answer 2

Answer:

answer is 5,250

Step-by-step explanation:

let cost of scooter is 9x

let cost of scooter is 9x and let cost of cycle=5x

let cost of scooter=9x and let cost of cycle =5x, we have 9x-5x=4,200

let cost of scooter =9x and let cost of cycle =5x,we have 9x-5x=4,200,x=1,050

let cost of scooter, =9x and let cost of cycle =5x,we

have 9x-5x=4,200,x=1,050

cost of price of cycle=5x1,050 = RS 5,250
