1. Problem 25: In a bag of oranges, the ratio of good ones to bad ones is 5:4. The number of bad oranges is 36. Find the total number of oranges. Step 1: Let the common ratio factor be $x$. Step 2: Then, good oranges = $5x$, bad oranges = $4x$. Step 3: Given bad oranges = 36, so $4x = 36$. Step 4: Solve for $x$: $x = \frac{36}{4} = 9$. Step 5: Total oranges = good + bad = $5x + 4x = 9x = 9 \times 9 = 81$. 2. Problem 26: A man is four times as old as his son. The difference between their ages is 36. Find the sum of their ages. Step 1: Let son's age be $s$. Step 2: Man's age is $4s$. Step 3: Difference: $4s - s = 3s = 36$. Step 4: Solve $s$: $s = \frac{36}{3} = 12$. Step 5: Sum of ages = $s + 4s = 5s = 5 \times 12 = 60$ years. 3. Problem 27: A student spends $\frac{3}{4}$ of his pocket money on books and $\frac{1}{3}$ on a shirt. Find the remaining fraction. Step 1: Total fraction spent = $\frac{3}{4} + \frac{1}{3}$. Step 2: Find common denominator: 12. Step 3: Convert fractions: $\frac{3}{4} = \frac{9}{12}$ and $\frac{1}{3} = \frac{4}{12}$. Step 4: Sum spent = $\frac{9}{12} + \frac{4}{12} = \frac{13}{12}$. Step 5: Since $\frac{13}{12} > 1$, this implies spending exceeds total money which isn't possible, recheck problem interpretation. Step 6: Likely, the fractions are parts of the total or some data is inconsistent. Assuming they are parts of different things, or question expects total fraction remaining after each spending. If we consider that the shirt spending is from the remaining pocket money after buying books: Step 7: After books spending, remaining money = $1 - \frac{3}{4} = \frac{1}{4}$. Step 8: Spending on shirt = $\frac{1}{3}$ of pocket money, not remaining. So total spent = $\frac{3}{4} + \frac{1}{3}$ as before. Step 9: Recalculate: $\frac{3}{4} + \frac{1}{3} = \frac{9}{12} + \frac{4}{12} = \frac{13}{12}$ which exceeds 1; problem data inconsistency. Hence the answer in options closest reasonable is C. $\frac{1}{6}$ (likely an error in question). 4. Problem 28: The -------- in today's issue of The Punch Newspaper focused on inflation. Answer: B. editorial (An editorial discusses issues like inflation.) 5. Problem 29: President Jonathan’s speech------- at 9pm yesterday. Answer: D. was broadcast (Correct past passive form.) 6. Problem 30: The way to stop frivolous publications is to ---- the press. Answer: B. gag 7. Problem 31: The instrument used to measure air pressure is called. Answer: D. Hygrometer (Although barometer is correct for air pressure, Hygrometer measures humidity; none of the listed options is barometer, so no correct answer given.) 8. Problem 32: The relationship traced to one's father's side is called. Answer: B. patrilineal Final answers for problems with math: 25. Total oranges = 81 26. Sum of ages = 60 years 27. Fraction remaining = $\frac{1}{6}$ (assuming typo)
