Question

the difference between 75%of a number and 20%of the same number is 378.4.what is 40%of that number?​

Answer 1

Step-by-step explanation:

let the no be x

75%of x- 20%ofx=378.4

55%of x=378.4(subtracting 20%from75%)

x= 3784/10 * 100/55

therefore , x =688

Now 40% of 688

40/100 *688= 275.2
