Question

If a number 'a' is 30% less than another number 'b', and 'b' is 20% more than 150, then what is the value of 'a'?

a. 96
b. 105
c. 112
d. 120

Answer 1

The answer is B. 105 as 150 minus 30% equals to 105

Answer 2

The number 'a' is found by calculating 20% more than 150 to get 'b', and then finding 'a' as 30% less than 'b'. The final value of 'a' is 126, which is not listed in the provided choices.

Step-by-step explanation:

We are given two pieces of information: the number b is 20% more than 150, and the number a is 30% less than b. First, we need to calculate the value of b:

b = 150 + (20% of 150)

= 150 + (0.20 × 150)

= 150 + 30

= 180

Now we can find the value of a, which is 30% less than b:

a = b - (30% of b)

= 180 - (0.30 × 180)

= 180 - 54

= 126

The value of a is 126, which is not among the options provided. Hence, there might be an error in the options given, or the question may have some misinterpretation.
