Question

With a total budget of $\$$12.75, the quantity of oranges over 7 kg that can be bought for $0.75 per kg is .

• A. 7.5 kg
• B. 10 kg
• C. 12.5 kg
• D. 15 kg

Answer 1

The correct option is B 10 kg

Given,
Total budget = $\$$12.75
Price per kg = $\$$0.75
Let the extra quantity of oranges
= $x$ kg

So,
Cost of oranges per kg × (7 + Extra quantity of oranges) = Total budget

$⟹$0.75 x (7 + $x$) = 12.75

$⟹$ $\frac{0.75}{0.75}$(7 + $x$) = $\frac{12.75}{0.75}$

$⟹$ (7 + $x$) = 17

$⟹$ $x$ = 17 - 7

$⟹$ $x$ = 10

$\therefore$ The extra quantity of oranges over
7 kg is 10 kg.
