The value of is (0.0203×2.92)/(0.7×0.0365×2.9) ÷ (12.12)2 - (8.12)2)/(0.25)2+(0.25)(19.99) :
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 0.05
Concept
Calculation
Identity = (a - b) ( a + b) = (a2 - b2)
Application
{(203 × 292 × 1 / 106 )/(7 × 365 × 29 × 1 / 10 6 )} ÷ { (12.12 - 8.12) / ((0.25)2+(0.25)(19.99))}
{292/365} ÷ {(4) x (20.24) / (0.25)(20.24)}
= 0.8/16 = 0.05
