Explanation

1. Let the breadth of rectangle be x metre.

Length = (x +4) metre

X (x +4) = 221 = 13 × 17

X =1 3metre

2. Let Vijay’s present age = x years

Suraj’s present age = 6x years

6x –x = 20

5x = 20 => x = 4

Suraj’s present age = 6 × 4 = 24 years

3. Let the number be x.

5. Let the amount with ajit be Rs. x.

Amount with Anuj =Rs. (x – 26)

Amount with Ravi = Rs. (x – 86)

x + x – 26 + x – 86 = 200

3x = 200 + 112 = 312

6. Marks obtained by the candidate = 230 – 38 = 192

7. M₁D₁= M₂D₂

15 × 20 = M₂ × 25

8. The word SOME has 4 distinct letters

Number of arrangements = 4! = 4 × 3 × 2 × 1 = 24
