Question

If the number B is 10% less than
another number C and C is 5%
more than 150, then B is equal to​

Answer 1

Answer:

149.9

Step-by-step explanation:

Let B be x and C be y

x=y-10%________(1)

y=5%+150________(2)

From 1 and 2

x=1÷10-y reduction of percentage

y=1÷20+150

y=1+3000÷20

y=3001÷20

Putting value of y in (1)

x=3001÷20-1÷10

x=3001-2÷20 LCM AS 20

x=2998÷20

x =149.9
