Hey dear, here is your answer.....

I expect you will find it helpful..

___________________________

1. In question 1, you have described half

of the question. The whole question is

like this:-

If L varies directly as M.

(¡) write an equation which relates L and

M.

(¡¡) Find the constant of proportion(k),

when L is 6 then M is 18.

(¡¡¡) Find L, when M is 33.

(¡v) Find M, when L is 8.

As, you want the answer of (¡¡¡) , (¡v), I will

answer these.

Now,

First, find constant based on question (¡¡)

Constant K = l/m = 6/18 = 1/3

(¡¡¡) Find L when M is 33

=> L = MK

=> L = 33 × 1/3

=> L = 11

(¡v) Find M when L is 8.

=> M = LK

=> M = 8 × 1/3

=> M = 8/3

72. Rate = SI × 100

P × T

= 500 × 100

2000 × 3

= 25/3% Rate of 1st

equation

SI = P × R × T

100

= 36000 × 25 × 3

100 × 3

= ₹9000

___________________________

73. The Mass = M , Length = L

According to the rule of Direct

proportioality:

=> M = K

L

=> 192 = K

16

=> 12 = K => K = 12

In 2nd equation:-

M = 105g, K = 12

=> L = M

K

=> L = 105

12

=> L = 8.75m

74. I have answered this question with

an image given above.

___________________________

75. He Walks 250 steps to cover = 200m

=> He will walk 1 step to cover =

200/250 m

=> He will walk 350 steps to cover

= 200 × 350

250

=> Total distance he will cover = 280 m.

___________________________

76. Car travels distance of 225 km in =

25 l of petrol

=> Car will travel distance of 1 km in =

25/225 l of petrol.

=> Car will travel distance of 540 km in

= 25 × 540

225

=> Car will cover total distance of 60 m.
