Question

The following ingredients are used to make bread:

Sugar: 20% of __ kg
Milk: 40% of 850 L
Flour: 40% of 700 kg

If the total bread made weighs 750 kg, find the weight of the sugar packet used ?

(Assume: 1 g = 1 ml)

• A. 250 kg
• B. 500 kg
• C. 650 kg
• D. 850 kg

Answer 1

The correct option is C 650 kg

Let the weight of sugar packet used be x kg.
Sugar = 20% of x kg
Milk = 40% of 850 L
Flour = 40% of 700 kg

Given, 1 mL = 1 g $\Rightarrow$ 1 L = 1 kg

Adding the weights of all the components and framing an equation where the total weight adds to 750 kg.

$\Rightarrow$ $\frac{20}{100}$ × x + $\frac{40}{100}$ × 850 + $\frac{40}{100}$ × 700
= 750

$\Rightarrow$ 0.2x + 340 + 280 = 750

$\Rightarrow$ 0.2x = 750 - 620

$\Rightarrow$ 0.2x = 130

$\Rightarrow$ x = 650

Therefore, weight of sugar packet used is 650 kg.
