Question : The monthly incomes of Ravi and Shiv are in the ratio 1 : 2 and their monthly expenditures are in the ratio 1 : 3. If each saves INR 4,000 per month, then find the monthly income of Shiv.
Option 1: INR 16,000
Option 2: INR 18,000
Option 3: INR 14,000
Option 4: INR 20,000
Correct Answer: INR 16,000
Solution : Let the monthly income of Ravi and Shiv be $x$ and $2x$. According to the question, $\frac{x-4000}{2x-4000}=\frac{1}{3}$ ⇒ $3x-12000=2x-4000$ ⇒ $x=8000$ Thus, the monthly income of Shiv = $2x=2\times8000=16000$ Hence, the correct answer is INR 16,000.
Question : If two successive discounts, each of 20% on the marked price of an article, are equal to a single discount of INR 331.20, then the marked price (in INR) of the article is:
Option 1: 920
Option 2: 750
Option 3: 1,200
Option 4: 645
Correct Answer: 920
Solution : Each discount = 20% Single discount = INR 331.20 Let the marked price be INR $x$. 1st discount at the marked price = (100 – 20)% of $x$ = 80% of $x$ = $\frac{80}{100}$ × $x$ = 0.8$x$ 2nd discount = (100 – 20)% of
Question : If $x = 5.51, y = 5.52$, and $z = 5.57$, then what is the value of $x^3+y^3+z^3-3xyz$?
Option 1: 5.146
Option 2: 51.46
Option 3: 0.05146
Option 4: 0.5146
Correct Answer: 0.05146
Solution : Given: The values of $x = 5.51, y = 5.52$, and $z = 5.57$ Use the algebraic identity, $x^3+y^3+z^3-3xyz=\frac{1}{2}(x+y+z)[(x-y)^2+(y-z)^2+(z-x)^2]$ So, $x^3+y^3+z^3-3xyz$ $=\frac{1}{2}(5.51+5.52+5.57)[(5.51-5.52)^2+(5.52-5.57)^2+(5.57-5.51)^2]$ $=\frac{1}{2}\times 16.6\times [(–0.01)^2+(–0.05)^2+(0.06)^2]$ $=8.3\times [0.0001+0.0025+0.0036]$ $=8.3\times 0.0062=0.05146$ Hence, the correct answer is 0.05146.
