Answer 1

Answer:

D. 150

Step-by-step explanation:

Let the number be ‘x’.

Then it’s 60% is (60/100)×x

=3x/5

If 60 is added to it,then 60+3x/5

Case (i): If x=60+3x/5,then

=> x=150.

Case (ii): If x>60+3x/5 , then

=> 2x/5 > 60

=> x > 150.

Case (iii): If x<60+3x/5, then

=> 2x/5 < 60

=> x <150.

Hope it helps !! :D

Answer 2

Step-by-step explanation:

60= 100x-60x/100

60=40x/100

60*100/40=X

150=X
