### Important Questions on Class 7 Maths Chapter 8

### Find the ratio of â‚¹5 to 50 paise.

â‚¹5 to 50 paise

= 5 x 100 paise to 50 paise [â‚¹ 1 = 100 paise]

= 500 paise to 50 paise

Thus, the ratio = 500/50 = 10 : 1

### I buy a T.V. for â‚¹10,000 and sell it at a profit of 20%. How much money do I get for it?

The cost price of T.V. = â‚¹ 10,000

Profit percent = 20%

Now,

Profit = Profit% of C.P. = 20/100 x 1000 = â‚¹ 2,000

Selling price = C.P. + Profit = â‚¹10,000 + â‚¹2,000 = â‚¹ 12,000

Hence, he gets â‚¹12,000 on selling his T.V.

##### About NCERT Solutions for Class 7 Maths Chapter 8

In 7 Mathematics Chapter 8 Comparing Quantities, we will study actually ratio and proportions in practical life. Some time we need to convert numbers into percentage. Percentages are numerators of fractions with denominator 100. Per cent is derived from Latin word â€˜per centumâ€™ meaning â€˜per hundredâ€™. Percentage when the total does not add to give 100. In the case, we multiply the fraction by 100/100. This does not change the value of the fraction. Subsequently, only 100 remains in the denominator. In this chapter we practice the questions based on â€“

1. Converting fraction into percent and vice versa.

2. Converting decimal into percent and vice versa.
