✪ Question ✪

If 1 is Subtracted from a number and the difference is mutliplied by 1/2, the result is 7. Find the number.

✪ Given ✪

When 1 is Subtracted from a number and the difference is mutliplied by 1/2, the result is 7.

✪ To find ✪

The number.

✪ Solution ✪

Let the number be x.

According to condition,

(x-1)×1/2 = 7

↝x-1 = 7÷1/2

↝x-1 = 7×2

↝ x-1 = 14

↝ x = 14+1

↝ x = 15

✪ Hence ✪

☞ x = 15

✪ Therefore ✪

The number is 15.

-------------------------------------------------------------

✪ Verification ✪

(x-1)×1/2 = 7

↝ (15+1)×1/2 = 7

↝ 14×1/2 = 7

↝ 14/2 = 7

↝ 7 = 7

So, L.H.S = R.H.S.

Hence, verified.
