Question : 36

Total: 40

2: 5

Solution:

Concept:

A ratio divides a total into parts; here, cement forms

2

parts out of a total of

2+5=7

parts.

Explanation:

Total parts in the ratio

2:5

are

2+5=7

These

7

parts together weigh

35\ \mathrm{kg}

So, one part weighs

\frac{35\ \mathrm{kg}}{7}=5\ \mathrm{kg}

Cement is

2

parts, so its mass is

2 \times 5\ \mathrm{kg}=10\ \mathrm{kg}

Answer:

The mixture contains

\mathbf{10\ kg}

of cement.

Correct option: B.
