Hello Friend

Here is your answer

Let the number is x

ATQ

 \frac{65}{100}  \times x -  \frac{2}{5}  \times x = 140 \\  \\  \frac{65x - 40x}{100}  = 140 \\  \\  \frac{25x}{100}  = 140 \\  \\ x =  \frac{140 \times 100}{25}  \\  \\ x = 140 \times 4 \\  \\ x = 560
Therefore Number is 560

Now We find 30% of 560
 =  \frac{30}{100}  \times 560 \\  \\  = 168
Therefore 30% of the number is 168.

Hope it helps you
