Fractions and Decimals [(0.05)² + (0.41)² +(0.073)²] / [(0.005)² + (0.041)² + (0.0073)²] = ? 100000 1000 10000 100 100000 1000 10000 100 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Given expression = [(0.05)² + (0.41)² +(0.073)²] / [(0.005)² + (0.041)² + (0.0073)²] Which is in form of [(a² + b² + c²)] /[ (a/10)² + (b/10)² + (c/10)²] = 100 x (a² + b² + c²) / (a²+b²+c²) = 100
Fractions and Decimals A vessel, full of water, weighs 16.5 kg. When the vessel is (1/4)th full, it weight 5.25 kg. Then, weight of the empty vessel (in kg) is ? 1.5 kg 100.5 kg 10.5 kg 1000.5 kg 1.5 kg 100.5 kg 10.5 kg 1000.5 kg ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Let the weight of vesel = x kg Then, 1/4 of volume of water = (5.25 - x)kg Full volume of water = (16.5 - x)∴ 4(5.25 - x) = (16.5 - x)⇒ 21 - 4x = 16.5 - x ⇒ 21 - 16.5 = 3x ∴ x = 4.5/3 = 1.5 kg
Fractions and Decimals If 0.12 ÷ x² = 12, than x = ? 0.1 10 0.001 0.01 0.1 10 0.001 0.01 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP 0.12 ÷ x² = 12 => 0.12/x² = 12=> x² = 0.12/12 = 0.01 => x = 0.1
Fractions and Decimals What should be subtracted from the multiplication of 0.527 and 2.013 to get 1 ? None of these 6085.1 60.851 0.060851 None of these 6085.1 60.851 0.060851 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP ∵ 0.527 x 2.013 = 1.060851Hence, the required number = 1.060851 - 1 = 0.060851.
Fractions and Decimals Which of the following fraction is arranged in ascending order of their value? 1/4, 2/7, 4/7, 5/7, 3/4, 6/5 2/7, 1/4, 4/7, 5/7, 3/4, 6/5 2/7, 1/4, 4/7, 3/4, 5/7, 6/5 1/4, 2/7, 3/4, 4/7, 5/7, 6/5 1/4, 2/7, 4/7, 5/7, 3/4, 6/5 2/7, 1/4, 4/7, 5/7, 3/4, 6/5 2/7, 1/4, 4/7, 3/4, 5/7, 6/5 1/4, 2/7, 3/4, 4/7, 5/7, 6/5 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Converting the given fractions into decimal numbers, we have1/4 = 0.252/7 = 0.283/4 = 0.754/7 = 0.575/7 = 0.716/5 = 1.2So, 0.25 < 0.28 < 0.57 < 0.71 < 0.75 < 1.2Corresponding fraction is 1/4 < 2/7 < 4/7 < 5/7 < 3/4 < 6/5
Fractions and Decimals If √5 = 2.24, then the value of 3√5 / 2√5 - 0.48 is ? 16.8 None of these 168 1.68 16.8 None of these 168 1.68 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Given expression = 3√5 / 2√5 - 0.48= (3 x 2.24) / (2 x 2.24) - 0.48= 6.72 / 4.48 - 0.48 = 6.72 / 4 = 1.68
