Answer 1

Answer:

(A) 48

Step-by-step explanation:

Here,

Weight reduced is directly proportional to days required.

Let he should walk 'x' more days.

Therefore,

$\frac{30}{5} = \frac{x}{8}$

$x = \frac{30 \times 8}{5}$

$x = 6 \times 8$

$x = 48$

Ans. He should walk at the same speed for 48 more days.

Answer 2

Speed of weight loss = 5/30 = 1/6

if want to loss 5+8 kg = 13 * 6. = 78 days

so he have to work 78-30 = 48 days
