From these 5 question, solve one question.


Plz solve the problem for me. I request you Plz..........​

Answer 1

Answer:

Solving question no.12.

Passing % = 40%.

Marks obtained = 322.

Marks by which he failed = 18.

So, passing marks = (322+18)=340.

Let the total marks be x.

Atq, 40% of x = 340.

=> 40x/100 =340.

=> x = 340 × 100/40.

Therefore x = 850.

Answer 2

Answer:

I'll solve question 10

let the required number be x

therefore 75% of that no. will be 75% ×x

ATQ, x = 75+75/100×x

x = 75+3x/4

x-3x/4 = 75

( 4x-3x)/4 = 75

x = 75×4

x= 300
