Question

Help me asap do only Q7) AND Q9) pls ty
give step by step explanation pls

Answer 1

Q 7) First Number = 12

Second Number = 24

Third Number = x

Fourth Number = 82

Therefore, 12:24 :: x:82

12/24 = x/82

NOW APPLY CROSS MULTIPLICATION METHOD.

x *24 = 82*12

24x = 984

x = 984/24

x = 41

therefore, the third number is 41.

Qn 9) 200 parts - 12 defective.

400 parts - 12+12 = 2 defective.

( 200 + 200 parts).

800 parts = 12+24= 36 parts .

(400+200 parts).

Hope it helps you.
