Explanation
(1.13+0.064)/(1.1?2-0.44+0.16) = (1.13+0.43)/(1.12-1.1x0.4+0.42 ) = ((1.1+0.4)(1.12-0.44 +0.42))/(1.12-0.44+0.42 ) = 1.5
Answer : D
Explanation
(0.72 +0.62 +0.52)/(0.072 +0.062 +0.052 )= (0.72 +0.62 +0.52)/0.12(0.72 +0.62 +0.52 ) = 1/.01 = 100
Answer : B

0.0169 / 0.013 = 0.0169/ 0.0130 = 169/130 = 13/10 = 1.3
Answer : C
Explanation
0.13 / x2 = 13 => 13x2 = 0.13 => x2 = 0.13/13 = 13/100 x 1/13 = 1/100 => x = 1/10 = .1
Answer : A
Explanation
As a3 + b3 = (a+b)(a2-ab + b2) Thus (a3 + b3) / (a2-ab + b2) = a + b ∴ (0.733 + 0.273) / (0.732 + 0.272 - 0.73 x 0.27) = 0.73 + 0.27 = 1
Answer : D
Explanation
3/5 = 0.6, 2/3 = 0.6666 Now 2/5 = 0.4 , 1/3 = 0.3, 1/15 = 0.066 and 31/50 = 0.62 Thus 31/50 is the correct answer.
