Question
‘P’, ‘Q’ and ‘R’ rented a power generator for
their stalls. They used it for 4 hours, 7 hours, and 5 hours respectively. The total rent they paid was Rs. 800. How much did ‘R’ pay?Solution
ATQ,
Let the dealer charged Rs. ‘x’ per hour.
Then the amount paid by ‘P’, ‘Q’ and ‘R’ is Rs. 4x, Rs. 7x, and Rs. 5x respectively.
So, 4x + 7x + 5x = 800
⇒ 16x = 800
⇒ x = 50
Rent paid by ‘R’ = 5x = 5 × 50 = Rs. 250
