Identify the correct mathematical statements:

1.A batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3. Then his average after 17th inning is 36.

2.The value of a number substracted from Numerator and Denominator of the fraction 6/7 to get a fraction equal to 3/4 is 3.

3.If 15% of 40 is greater than 25% of a number by 2, then the number is 16.

4.The value of (1+1/2)(1+1/3)(1+1/4) ........ (1+1/120) is 60.5

A2, 3 & 4 only ✓ Correct

B2 & 3 only

C3 & 4 only

D1 & 2 only

Correct answer: (A) 2, 3 & 4 only

Explanation

Statements 2, 3 and 4 are correct.

Statement 1: 16(x-3)+87 = 17x gives x = 39, not 36.

Statement 2: (6-a)/(7-a) = 3/4 gives a = 3.

Statement 3: 15% of 40 = 6 = 0.25n + 2 gives n = 16.

Statement 4: the telescoping product = 121/2 = 60.5.
