**Explanation**

1. Let the number be x.

According to the question,

11x = 378.4 × 20

40 % of 688

2. Gain in length = 100 cm – 95 cm = 5 cm

Gain per cent

3. Let one integer be x.

Other integer = x + 15

According to the question,

108 + x + x 15 + 29 = 4 × 73.5

2x +1 52 = 294

2x = 294 – 152 = 142

4. SI = Rs. (26350 – 21250) = Rs. 5100

5. CP of a walkman

= Rs. 750

6. A = 25 % of B

Hence, B is 400 % of A.

7.

= 54 km/h

8. Let the present ages of father and son be 5x and x years respectively.

According to the question,

5x + 7 = 3x + 21

2x = 14

Son’s present age = 7 yr

9.

?

^{2} = 32 × 648

?= 144

10. Area of the rhombus

Area to be painted = 2 × 40 = 80 m

^{2}
Hence, the required cost = Rs. 80 × 70 = Rs. 5600
