Question

please solve this problem

Answer 1

x% of y = 10
-> x/100×y = 10
xy/100= 10
xy= 1000

y% of 120= 48
-> y/100×120=48
->y/5×6=48
-> y= 48×5/6
y= 40

xy = 1000
x×40=1000
x= 1000/40
x=25

Therefore option (A) is correct.

hope it helps.....

Answer 2

x% of y = 10

x / 100 * y = 10

x * y = 10 * 100

xy = 1000 - (i)

y% of 120 = 48

y / 100 * 120 = 48

y = 48 * 100 / 120

y = 40 - (ii)

From equation (i)

xy = 1000

From equation (ii)

x * 40 = 1000

x = 1000 / 40

x = 25

So, option A) 25 is the correct answer.
