Question

1). The population of ranjan village is 4500. the ratio of literates to illiterates is 3:7 Determine the number of illiterates in the village. Solve in step by steps​

Answer 1

Answer = 3150

Step-by-step explanation:

population = 4500

Let no. to be multiplied = x

Ratio = 3:7

Now, 3x + 7x = 4500

10x = 4500

x = 4500/10

x = 450

Now, Illiterate people = 7x = 450 * 7 = 3150

Answer 2

Answer:

3150

Step-by-step explanation:

Given:

• Total population = 4500
• Ratio of literates to illiterates = 3 : 7

To find:

• No. of illiterates = ?

Solution:

We are given with the ratio of literate to illiterate as 3 : 7.

Let the actual no. of literates people be 3x,

no. of illiterates people be 7x.

Now, we know that literate + illiterate will give us total population.

⇒ 4500 = 3x + 7x

⇒ 4500 = 10x

⇒ 4500/10 = x

⇒ 450 = x

The value of 'x' we got is 450.

We know that no. of illiterates is 7x,

⇒ 7x = 7 × 450

⇒ 3150

Hence, number of illiterates in the village = 3150.
