Total income = Mujahid's income + Wife's income
= 56,835 + 35,600 = 92,435
Expenditure = Rs 65,000
Savings = Income − Expenditure
= 92,435 − 65,000 = 27,435
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.
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.
To find the number: 15 ÷ 0.20 = 75
So, 15 is 20% of 75.
A number is exactly divisible by 5 if it ends in 0 or 5.
230590 ends in 0, so it is divisible by 5.
The symbol ∩ represents the common elements between two or more sets.
For example, if A = {1, 2, 3} and B = {2, 3, 4}, then A ∩ B = {2, 3}.
Given y ∝ x, we can write y = kx.
When x = 5, y = 210:
210 = k(5)
k = 210/5
k = 42
Now, when x = 2:
y = kx
y = 42(2)
y = 84
