Question
The LCM of two numbers is 150, and the numbers are in the
ratio 2:5. What will be the sum of the numbers?Solution
ATQ,
Let the numbers be 2m and 5m.
LCM of the numbers = 10m
Given, 10m = 150
So, m = 15
Thus, the numbers are 30 and 75.
Hence, the sum = 30 + 75 = 105.
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
(4.89)2 + √144.35 - √121.25 = ?
?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
(√4623.9 + √484.2) – √2303.97 ÷ √1296.4 × √35.98 ÷ √15.99 = ?
[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
