Answer 1

Answer:

Option d

Step-by-step explanation:

Given:-

The number B is 10% less than another number C and C is 5% more than 150

To find:-

Find the number B?

Solution:-

Given that

C is 5% more than 150

5% of 150

=>(5/100)×150

=>(5×150)/100

=>750/100

=>7.5

Now C = 150+5% of 150

=>C = 150+7.5

=>C = 157.5

The number C = 157.5

Now ,

Number B = 10% less than C

10% of C =

=>10% ×157.5

=>(10/100)×157.5

=>(1/10)×157.5

=>157.5/10

=>15.75

Now, B = C-10% of C

=>B = 157.5 - 15.75

=>B= 141.75

Answer:-

The number B for the given problem is 141.75
