Explanation

For collinear points, slope between any two pairs is equal:

Slope(1,2) & (4,m) = Slope(4,m) & (5,6)

(m-2)/(4-1) = (6-m)/(5-4)

(m-2)/3 = 6-m

m-2 = 18-3m

4m = 20

m = 5

Explanation

Let's assume the interest rate is 12% p.a. (common in Pakistan):

Interest = Principal × Rate × Time

54,000 = P × 0.12 × 3

P = 54,000 / (0.12 × 3)

= 54,000 / 0.36

= 150,000

Explanation

Work done by 40 men in 40 days = 1/3 of total work

Total work = 3 × (40 × 40) = 4800 man-days

Remaining work = 2/3 of total work = 3200 man-days

Time left = 50 days

Men required = 3200 ÷ 50 = 64 men

Additional men needed = 64 − 40 = 24 men

Therefore, 24 more men are required.

Explanation

Let's solve the equation:

4^(2n+3) = 8^(n+5)

Expressing both sides with base 2:

(2^2)^(2n+3) = (2^3)^(n+5)

2^(4n+6) = 2^(3n+15)

Equating exponents:

4n + 6 = 3n + 15

4n - 3n = 15 - 6

n = 9

Explanation
