Explanation

Let's break it down:

Total amount = Rs. 2400

Nida's share = Rs. 600

Remaining amount = Rs. 2400 - Rs. 600 = Rs. 1800

Nadia and Amara share the remaining amount in the ratio 4:5.

Let's divide Rs. 1800 in the ratio 4:5:

Total parts = 4 + 5 = 9

Amara's share = (5/9) × Rs. 1800

= Rs. 1000

Explanation

a:b = 8:9, b:c = 6:5

Make b same:

a:b = 16:18, b:c = 18:15

So, a:b:c = 16:18:15

Explanation

Given:

Hyder’s investment = Rs. 90,000

Ahsan’s investment = Rs. 60,000

Total profit = Rs. 45,000

Step 1: Find the ratio of their investments

Hyder : Ahsan = 90,000 : 60,000 = 3 : 2

Step 2: Divide the profit in the ratio 3:2

Total parts = 3 + 2 = 5

Ahsan’s share = (2/5) × 45,000 = Rs. 18,000

Explanation

To increase 76 in the ratio 5:2, we need to multiply 76 by 5/2.

New value = 76 × 5/2

= 76 × 2.5

= 190

Explanation

Given a : b = 2 : 3 and b : c = 3 : 4

Since b is common in both ratios, we can directly combine the ratios:

a : b : c = 2 : 3 : 4

Explanation

= 18 × 1/6

= 3

Explanation

Equating the two expressions and simplifying gives:

$$x cdot 200 = y cdot 250 Rightarrow frac{y}{x} = frac{200}{250} = frac{4}{5} Rightarrow y : x = 4 : 5$$

⇒y​/x=200/250

=4​/5

⇒y:x=4:5
