The numbers are 2x, 3x, and 4x with an HCF of 12. So, x = 12.
Numbers are 24, 36, and 48.
Calculating LCM
LCM(24, 36, 48) = 2^4 * 3^2 = 144
If U is the universal set and B = {2,4,6,8}, then U – B gives the complement of B.
So, U – B = {1,3,5,7}, which are elements in U not in B.
640 × 1.50 = 960
So, the total cost of 640 photocopies at Rs. 1.50 each is Rs. 960.
Whole numbers are non-negative integers: 0, 1, 2, 3…
0 is a whole number.
The square root of 1/4 is:
√(1/4) = √1 / √4
= 1/2
The diamond symbol is placed at -3 on the number line, it directly matches the position mentioned.
Since symbols on a number line represent specific values, the diamond at -3.
The intersection of two sets X and Y (X ∩ Y) is the set of elements that are common to both X and Y.
Given:
X = {2, 4, 6, 8}
Y = {1, 2, 3, 6}
The common elements are 2 and 6.
So, X ∩ Y = {2, 6}.
The greatest 5-digit number is 99999.
Adding 2 gives 99999 + 2 = 100001, which is 1 more than the smallest 6-digit number (100000).
Let's identify the prime numbers from the list:
