Question

if half of a number added to three- fourth of a number gives 25 by 2 find the number

Answer 1

Answer:

Let the number be y

y/2 + 3y/4 = 25/2

LCM = 4

2y+3y/4 = 25/2

5y/4 = 25/2

2(5y) = 25(4)

10y = 100

y = 10

VERIFY:

25/2 = 12.5

10/2 = 5

3/4(10) = 7.5

y/2 + 3y/4 = 25/2

5 + 7.5 = 12.5

12.5 = 12.5

LHS = RHS

Hence, verified
