Answer 2

x = 16.5

Step-by-step explanation:

Let 1/5 of a number be x/5.

According to the condition

x/5+37/10 = 7

Therefore,

2x/10+37/10 = 7... L. C. M

Therefore,

2x+37/10 = 7

Therefore,

2x+37 = 70... Multiply Equation By 10

Therefore,

2x = 70 - 372

x = 33

x = 33/2

Therefore,

x = 16.5

( Ans ) The Required Number is 16.5
