RRB NTPC · Question 66

The value of \(\frac{{11}}{5} - \left( {\frac{2}{3}of\frac{3}{5} - \frac{1}{5}} \right) + \left( {\frac{6}{5} \div \frac{4}{5}} \right)\)is:

  1. 1/5

  2. 3/5

  3. 2/3

  4. 7/2

Show answer & explanation

Answer: (D) 7/2

Explanation

2/3 of 3/5 = 2/5, so the bracket is 2/5 − 1/5 = 1/5. 6/5 ÷ 4/5 = 3/2. Value = 11/5 − 1/5 + 3/2 = 2 + 3/2 = 7/2.
