Question : The value of $\frac{0.325 \times 0.325+0.175 \times 0.175-25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}$ lies between:
Option 1: 0.35 and 0.45
Option 2: 0.15 and 0.25
Option 3: 0.25 and 0.35
Option 4: 0.05 and 0.15
Correct Answer: 0.25 and 0.35
Solution : Given: $\frac{0.325 \times 0.325+0.175 \times 0.175-25 \times 0.00455}{5 \times 0.0065 \times 3.25-7 \times 0.175 \times 0.025}$ $=\frac{0.325 \times 0.325+0.175 \times 0.175-2 \times 0.325\times0.175}{(0.325)^2- (0.175)^2 }$ $=\frac{(0.325 -0.175)^2}{(0.325+0.175)(0.325-0.175) }$ $=\frac{(0.325 -0.175)}{(0.325+0.175) }$ $=0.3$ Hence, the correct answer is 0.25 and 0.35.
Question : The speed of the current is 5 km/h. A motorboat goes 10 km upstream and back again to the starting point in 50 minutes. The speed (in km/h) of the motorboat in still water is:
Option 1: 20
Option 2: 26
Option 3: 25
Option 4: 28
Correct Answer: 25
Solution : Let the speed of the boat be $x$ km/h. Given: The speed of current = 5 km/h Therefore, upstream speed of boat = $(x-5)$ km/h Downstream speed of the boat = $(x + 5)$ km/h According to the question, $ \frac{10}{x-5}+\frac{10}{x+5}=\frac{50}{60} $ ⇒ $10 \left(\frac{x+5+x-5}{x^{2}-25}\right)=\frac{5}{6}$
Question : In a cricket match, there are three types of tickets say A, B, and C each costing Rs. 1000, Rs. 500, and Rs. 200 respectively. The ratio of the tickets sold in categories A, B, and C is $3:2:5$. If the total collection from selling the tickets is Rs. 2.5 crores. Find the total number of tickets sold.
Option 1: 5000
Option 2: 4800
Option 3: 50000
Option 4: 52000
Correct Answer: 50000
Solution : Let the number of tickets be $3n, 2n,$ and $5n$. According to the question, $(3n×1000)+(2n×500)+(5n×200) = 25000000$ ⇒ $3000n+1000n+1000n = 25000000$ ⇒ $5000n = 25000000$ ⇒ $n = \frac{25000000}{5000}$ $\therefore n= 5000$ So, total number of tickets $=(3n+2n+5n) = 10n= (10 × 5000) = 50000$
