Answer 1

Question:

If x% of 250 + 25% of 68 = 67, find x.

(a) 45

(b) 10

(c) 20

(d) 25

Answer:

Option(c) : 20

Solution;

We have;

=> x% of 250 + 25% of 68 = 67

=> (x/100)•250 + (25/100)•68 = 67

=> x•250/100 + 25•68/100 = 67

=> 25x/10 + 68/4 = 67

=> 5x/2 + 17 = 67

=> 5x/2 = 67 - 17

=> 5x/2 = 50

=> x = 50•2/5

=> x = 20

Hence,

The required value of x is 20 .

Answer 2

Answer:

x% of 250 + 25% of 68 = 67.

(x/100)•250 + (25/100)•68 = 67.

x•250/100 + 25•68/100=67.

25x/10 + 68/4 =67.

5x/2 + 17 = 67.

5x/2 = 67 - 17.

5x/2 = 50.

x = 50•2/5.

x = 20.
