G. C. D of 1.08, .36 and .9 is?

Correct Answer: 27

Explanation:

The given number are 3.00, 0.09 and 2.70
LCM = LCM of numerator / HCF of denominator
L. C. M of 300, 9 and 270 is 2700
? Required L.C.M = 27.00 = 27

Correct Answer: 100

Explanation:

Given expression = (0.01 - 0.0001) / (0.00001 + 1)
= (.0099 / .0001) + 1
= 99 + 1
= 100

Correct Answer: 1.5

Explanation:

Given expression = 3 / [ 3+ {(0.3 - 3.03) / (3 x 0.91)}]
= 3 / [3- { 273 / (3 x 91)}]
= 3 / (3-1)
= 3 / 2
= 1.5

Correct Answer: 1

Explanation:

Given Expression = ( a³ + b³ )/ (a² + b² - ab) where = 0.87 and b = 0.13
= [(a + b ) (a² + b² - ab)] / (a² + b² - ab)
= a + b
= 0.87 + 0.13
= 1

Correct Answer: 1

Explanation:

Given Expression = (1.04)² + 1.04 x 0.04 + (0.04)² / (1.04)³ - (0.04)³
= (a² + ab + b²) / (a³ - b³)
= (a² + ab + b²) / [(a-b) (a² + ab + b²)]
= 1 / (a - b)
= 1/ (1.04 - 0.04)
= 1

Correct Answer: 3/22

Explanation:

= 0.136
= (136 - 1) / 990
= 135 / 990
= 3 / 22

Correct Answer: 1.01 = ?

Explanation:

Given Exp. = 0.63 + 0.37
= 63/99 + 37/99
= 100 / 99
= 1¹/₉₉
= 1.01

Correct Answer: 0.4801

Explanation:

Given Exp= 0.3467 + 0.1333
= (3467 - 34) / 9900 + (1333 -13) / 9900
= 3433 +1320 / 9900
= 4753 / 9900
= (4801 - 48) / 9900
= 0.4801

Correct Answer: 1.43

Explanation:

Given Exp. = 3.57 - 2.14
= 3 + (57 / 99) - 2 - (14 / 99)
= 1 + (57 / 99) - (14 /99)
= 1 + 43/99
= 1.43

Correct Answer: 6.06

Explanation:

Given Exp. = 247 + 353 + 0.05
= 5 + (47 / 99) + (53 / 99) + (05 / 99)
= 5 + (105 / 99)
= 5+1⁰⁶/₉₉
=6⁰⁶/₉₉
= 6.06
