this question should be solved without using the calculator
24>23 hence 24/23 is greater than 1
101/100 = 1.01
sum= 1.01 + a number greater than 1. end result>2
(A)

• Quantity A is greater.
• Quantity B is greater.
• Both Quantities are Equal
• Cannot be determined


Given:
Quantity A: (24/23) + (101/100)
Quantity B: 2


I like to use "+" notation to represent "a little bit bigger than"
For example, I might rewrite 4.07 as 4+ to save time (and lengthy calculations)

Likewise, I use "-" notation to represent "a little bit smaller than"
For example, I might rewrite 6.98 as 7- to save time (and lengthy calculations)

So, 24/23 = 1+
And 101/100 = 1+

So, we get:
Quantity A: (1+) + (1+)
Quantity B: 2

Simplify to get:
Quantity A: 2+
Quantity B: 2

Answer: A

Here we don’t need to use our calculator.
24>23 and 101>100, each division is greater than 1
A>B

Just by looking at the problem one can discern that since the denominator is greater than numerator the quotient (solution of division ) has to 1.some decimal.

As we notice both the factions when added will result 2.(something) in decimals which is greater than 2.

Therefore option A is correct.
