Question

If 0.001 + 1.01 + 1.001 - (1.03 × 0.1) + (1.11 ÷ 0.1) + x = 1.4 × (1/10)^-1 then the value of x is
1. 0.758
2. 0.991
3. 0.919
4. 0.785

Answer 1

Correct Answer - Option 2 : 0.991

Calculation : 

0.001 + 1.01 + 1.001 - (1.03 × 0.1) + (1.11 ÷ 0.1) + x = 1.4 × (1/10)-1 

⇒ 2.012 - 0.103 + 11.1 + x = 1.4 × 10

13.112 - 0.103 + x = 14

13.009 + x = 14

∴ x = 14 - 13.009 = 0.991
