Answer» Correct Answer - Option 1 : 2 Here, we have to find the value of 1 + 1/2 + 1/4 + 1/7 + 1/14 + 1/28 Concept Used: 1/a + 1/b = (b + a)/ab Calculation: (1 + 1/2) + (1/4 + 1/7) + (1/14 + 1/28) ⇒ 3/2 + 11/28 + 3/28 ⇒ (42 + 11 + 3)/28 ⇒ 56/28 ⇒ 2 Hence, the value of 1 + 1/2 + 1/4 + 1/7 + 1/14 + 1/28 is 2 |
