Question

If 20 is subtracted from 4 times a number, we get 20. Find the number. If 121 is added to 11 times a number, it becomes 132. Find the number​

Answer 1

Answer:

If 20 is subtracted from 4 times a number, we get 20. The number be 10. If 121 is added to 11 times a number, it becomes 132. The number be 1.

Step-by-step explanation:

Let us consider the number be x.

Given,

        If 20 is subtracted from 4 times a number, we get 20.

             ⇒4 times a number-20=20

 

                 $4x-20=20-----------(1)\\ \\ 4x=20+20\\ \\ 4x=40\\ \\ x=10$

If 121 is added to 11 times a number, it becomes 132

             ⇒11 times a number+121=132

                   $11x+121=132\\ \\ 11x=132-121\\ \\ 11x=11\\ \\ x=1$

Answer 2

20 is subtracted 4 times. so total subtracted amount =20x4 =80

Suppose number is x. so the equation will be x-80=20,

So x = 20+80=100

It is the 1st number.

Same for the second.

121 is added 11 times. so total added amount is 121 x 11= 1331

Suppose the number is x. so the will be x+1331=132.

So x = 132-1331 = -1199.
