Answer: Option A

Explanation:

To find the greatest number that will divide 43, 91, and 183, leaving the same remainder in each case, you can use the following approach:

Find the differences between the numbers:

Difference between 91 and 43: 91 - 43 = 48
Difference between 183 and 91: 183 - 91 = 92

Now, find the greatest common divisor (GCD) of these differences: GCD(48, 92)

Calculate the GCD: GCD(48, 92) = 4

So, the greatest number that will divide 43, 91, and 183, leaving the same remainder in each case, is 4. Therefore, the answer is 4.

B. 99360
C. 99350
D. 99340

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

LCM of 16, 24, 30, 36 is 720

Highest 5 digit number 99999

Now, 99999÷720= 138 and remainder is 639

99999-639=99360

So, Highest 5 digit number that can be divided by 16, 24, 30, 36 without any remainder is 99360

As to leave 10 as remainder the 5 digit number should be, 99360+10=99370

Answer: Option C

Explanation:

The number that would be divisible by the L.C.M of 6, 20, 24 is the correct answer option
Now, the L.C.M of 6, 20,, 24 is found.
2 6, 20, 24
3 3, 10, 12
2 1, 10, 4
1, 5, 2
So L.C.M = 2×3×2×5×2=120

Now, only 960 is divisible by 120, so 960 is the correct answer.

A. 10003
B. 10093
C. 10073
D. 10013

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

To find the least five-digit number that satisfies these conditions, you need to find the least common multiple (LCM) of 8, 12, 16, and 20, and then add 1, 5, 9, and 13 to it. Here's the step-by-step process:

Find the LCM of 8, 12, 16, and 20:

LCM(8, 12, 16, 20) = 240

Add the remainders 1, 5, 9, and 13 to the LCM:

240 + 1 = 241 240 + 5 = 245 240 + 9 = 249 240 + 13 = 253

Now, find the least five-digit number among these values:

The least five-digit number is 10,000.

Check which of the values (241, 245, 249, 253) is the smallest one that is greater than or equal to 10,000:

The smallest value that satisfies this condition is 10,073.

So, the least five-digit number that can be divided by 8, 12, 16, and 20, leaving the remainders 1, 5, 9, and 13, respectively, is 10,073.

A. 10196
B. 10199
C. 10197
D. 10191

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Difference, 40 - 31 = 9
60 - 51 = 9
75 - 66 = 9
Difference between numbers and remainder is same in each case.
Then,
The answer = {(LCM of 40, 60, 75) - 9}
40 = 2 × 2 × 2 × 5
60 = 2 × 2 × 3 × 5
75 = 3 × 5 × 5
LCM = 2 × 2 × 2 × 5 × 5 × 3 = 600
But, the least number of 5 digits = 10000
10000/600, we get remainder as 400
Then, the answer = 1000 - (600 - 400) - 9 = 10191
