Explanation

Given:

1. Ten years ago, C's mother was 4 times as old as C:

10 years ago, C = 15 → mother = 4×15 = 60 → Now = 70

After 10 years, mother = 80 → 2×25 = 50

Explanation

We are given:

• 35 kg of spinach costs Rs. 28

• We need to find how many kg can be bought for Rs. 16

Step 1: Find cost per kg

Cost per kg==28​/35=0.8Rs/kg

Step 2: Find how many kg for Rs. 16

$$text{Kg} = frac{16}{0.8} = 20$$0.8=20

Explanation

We are given:

4/3​ of a number=22

Let the number be $x$. Then:

4/3​​x=22⇒x=22×3/4​=66/4​=16.5

Now, we need to find:

$$frac{8}{3}x = frac{8}{3} times 16.5 = frac{8 times 33}{6} = frac{264}{6} = 44$$

Explanation

We are given the equation:

$$7 - m = 12 - n$$

To find$n-m$, solve the equation step-by-step:

Step 1: Rearrange the equation

$$7 - m = 12 - n Rightarrow -m + n = 12 - 7 Rightarrow -m + n = 5 Rightarrow n - m = 5$$
