So, after that, she has = $\frac{100-15}{100}×17875=15193.75$ She saves 40% of the remaining income. So, her savings
Question : If $\sqrt[3]{N}$ lies between 6 and 7, where $N$ is an integer then how many values $N$ can take?
Option 1: 126
Option 2: 127
Option 3: 128
Option 4: 125
Correct Answer: 126
Solution : Given: If $\sqrt[3]{N}$ lies between 6 and 7, where $N$ is an integer. $6^3=216$ $7^2=343$ The cube root of 216 is 6 and the cube root of 343 is 7. Every number between 343 and 216 has a cube root between 6 and 7. The
Question : Find the sum of $\left (1-\frac{1}{n+1} \right) + \left (1-\frac{2}{n+1} \right) + \left (1- \frac{3}{n+1} \right)+.....\left ( 1- \frac{n}{n+1} \right)$.
Option 1: $n$
Option 2: $\frac{n}{2}$
Option 3: $(n+1)$
Option 4: $\frac{(n+1)}{2}$
Correct Answer: $\frac{n}{2}$
Solution : $\left (1-\frac{1}{n+1} \right) + \left (1-\frac{2}{n+1} \right) + \left (1- \frac{3}{n+1} \right)+.....\left (1- \frac{n}{n+1} \right)$ = $\frac{n}{n+1}+\frac{n-1}{n+1}+\frac{n-2}{n+1}+...........+\frac{1}{n+1}$ $= \frac{1}{(n+1)}\frac{[n(n+1)]}{2}$ $=\frac{n}{2}$ Hence, the correct answer is $\frac{n}{2}$.
Question : The salaries of Rida and Riya are in the ratio of 3 : 5, respectively. If the salary of each one is increased by Rs. 5,000, then the new ratio becomes 5 : 7. What is Riya’s present salary?
Option 1: Rs. 12,500
Option 2: Rs. 7,500
Option 3: Rs. 2,500
Option 4: Rs. 10,000
Correct Answer: Rs. 12,500
Solution : Let the present salaries of Rida and Riya be $3x$ and $5x$ respectively. According to the question, $(3x + 5000) : (5x + 5000) = 5 : 7$ ⇒ $21x + 35000 = 25x + 25000$ ⇒ $4x = 10000$ ⇒ $x = 2500$
