LCM of two numbers is 7700 and HCF is 11. If one number is 308 then other number is
269
285
300
275
Answer: Option D
Similar Questions :
1. The ratio of two numbers is 3 : 4 and their H.C.F. is 4. Their L.C.M. is
48
22
56
27
Answer: Option A
Explanation:
Let the numbers be 3x and 4x. Then, their H.C.F. = x. So, x = 4.
So, the numbers 12 and 16.
L.C.M. of 12 and 16 = 48.
2. Find the greatest number which on dividing 1661 and 2045, leaves a reminder of 10 and 13 respectively
125
127
129
131
Answer: Option B
Explanation:
In this type of question, its obvious we need to calculate the HCF, trick is
HCF of (1661 - 10) and (2045 -13)
= HCF (1651, 2032) = 127
3. Find the HCF of 2.1, 1.05 and 0.63
0.44
0.64
0.21
None of above
Answer: Option C
Explanation:
To solve this question quickly, first remove decimal by multiplying each term with 100,
Then terms become 210, 105, 63
Then HCF of above terms is 21,
So Answer is 0.21

Answer: Option C
Explanation:
Trick is HCF of (237-132), (132-62), (237-62)
= HCF of (70,105,175) = 35
