To find the loss percentage:
Cost Price (CP) = Rs. 120,000
Selling Price (SP) = Rs. 96,000
Loss = CP - SP = 120,000 - 96,000 = Rs. 24,000
Loss percentage = (Loss / CP) × 100
= (24,000 / 120,000) × 100
= 0.2 × 100
= 20%
Given:
x̄ (mean) = 12
∑x (sum) = 132
The formula for mean is:
x̄ = ∑x / n
Rearrange to find n:
n = ∑x / x̄
= 132 / 12
= 11
Sum of angles in a quadrilateral = 360°
Given angles:
Add them:
109 + 67 + 82 = 258°
Now subtract from 360°:
360° − 258° = 102°
A number is divisible by 4 if the last two digits form a number divisible by 4 — here, 48 ÷ 4 = 12.
92,348 ÷ 4 = 23,087 (no remainder), confirming exact divisibility.
When 16025 ÷ 1000, the quotient is 16 and the remainder is 25.
Because 1000 × 16 = 16000, and 16025 − 16000 = 25.
The fraction 1/3 equals 0.333... (repeating 3).
2. It is a non-terminating repeating decimal.
The square of a means multiplying a by itself, which is written as a².
It represents the value a × a.
To find when Mubashir and Ali will both exercise on the same day again, we need to calculate the Least Common Multiple (LCM) of their exercise days:
Mubashir: every 8 days
Ali: every 4 days
LCM of 8 and 4 = 8
They will both exercise again on the same day after 8 days.
