Question

If 10% of a number is 4 less than 20% of the same number, then find the number.
​

Answer 1

Answer:

40

Step-by-step explanation:

Let the number be 'x'. Then,

10% of 'x' --> 10/100×'x'

20% if 'x' --> 20/100×x'

Thus, the equation formed is

10x/100 = 20x/100 - 4

=> 2x/10 - x/10 = 4

=> x/10 = 4

=> x= 4×10

= x= 40

Therefore, the required number is 40.
