Or recognize as (x + y)² = (3 + 2)² = 25

7. What is the LCM of 18, 24, and 36?

17 25% of a number is 60. Find the number.

A) 200
B) 220
C) 240
D) 260

Explanation:

Let the number be X
25% of X = 60
0.25 × X = 60
X = 60 ÷ 0.25
X = 240
Alternatively: 25% is 1/4, so full number = 60 × 4 = 240

18 A number is increased by 20% then decreased by 20%. Net change?

A) 0%
B) 2% increase
C) 4% decrease
D) 4% increase

Explanation:

Let original number = 100
After 20% increase: 100 + (20% of 100) = 120
Then 20% decrease: 120 – (20% of 120) = 120 – 24 = 96
Net change: 100 → 96 (4% decrease)
Key point: The decrease is applied to a larger amount

19 Find: (45 × 23) – (45 × 3)

A) 810
B) 900
C) 950
D) 1080

Explanation:

Using distributive property: a×b – a×c = a×(b-c)
= 45 × (23 – 3)
= 45 × 20
= 900
Alternative method:
- 45 × 23 = 1035
- 45 × 3 = 135
- 1035 – 135 = 900

If profit = ₹240 and CP = ₹1200, profit % = ?

A) 15%
B) 18%
C) 20%
D) 25%

Explanation:

Profit Percentage = (Profit / Cost Price) × 100
= (₹240 / ₹1200) × 100
= 0.20 × 100
= 20%
Verification: 20% of ₹1200 = ₹240 (matches given profit)
