Question :
Directions: In the following question, you have to identify the correct response from the given premises stated according to the following symbols: If × means –; – means ×; + means ÷ and ÷ means +; then (15 – 10) ÷ (130 + 10) × 50 = ?
Option 1: 1800
Option 2: 113
Option 3: 2000
Option 4: 123
Correct Answer: 113
Solution : Given: × means –; – means ×; + means ÷ and ÷ means +. (15 – 10) ÷ (130 + 10) × 50 = ?
After replacing the symbols, the equation becomes – = (15 × 10) + (130 ÷ 10) – 50 = 150 + 13 – 50 = 163 – 50 = 113
So, 113 is the answer to the given equation. Hence, the second option is correct.
Question : A1, A2, and A3 alone can complete a piece of work in 12 hours, 24 hours, and 16 hours respectively. Working together, in how much time will they complete the same work?
Option 1: 5 hours 30 minutes
Option 2: 5 hours 20 minutes
Option 3: 4 hours 20 minutes
Option 4: 3 hours 30 minutes
Correct Answer: 5 hours 20 minutes
Solution : Time taken by A1 to do the work = 12 hours ⇒ 1 day's work of A1 = $\frac{1}{12}$ Time taken by A2 to do the work = 24 hours ⇒ 1 day's work of A2 = $\frac{1}{24}$ Time taken by A3 to do the work = 16 hours ⇒ 1 day's work of A3 = $\frac{1}{16}$ If A1, A2, and A3 work together, work will be done in a day = $\frac{1}{12}$ + $\frac{1}{24}$ + $\frac{1}{16}$ = $\frac{4+2+3}{48}$ = $\frac{9}{48}$ = $\frac{3}{16}$ So, Time taken by A1, A2, and A3 together to do the work = $\frac{16}{3}$ = $5\frac{1}{3}$ hours = 5 hours 20 minutes Hence, the correct answer is 5 hours 20 minutes.
