Question : A Microwave oven is sold in Hyderabad for Rs. M. A retailer, Elahi from Hyderabad went to Madras and bought it for 25% less (when compared to the price in Hyderabad). He spends Rs.1,000 on transport to bring it from Madras to Hyderabad. He sold it in Hyderabad for Rs. M making a profit of 10%. Find the value of M (in Rs.).

Option 1: 6,305.80

Option 2: 6,258.80

Option 3: 6,285.70

Option 4: 6,527.90

Team Careers360 19th Jan, 2024

Correct Answer: 6,285.70


Solution : Price at Hyderabad = Rs. M
Price at Madras is 25% less than that in Hyderabad
So, price at madras = M$\times 75\%=\frac{3}{4}$M
The cost price including transportation fee becomes $(\frac{3M}{4}+1000)$
For 10% profit on this cost price,
($\frac{3M}{4}$ + 1000)$\times \frac{110}{100}$ = M

Question : If $(4 y-\frac{4}{y})=13$, find the value of $(y^2+\frac{1}{y^2})$.

Option 1: $12 \frac{11}{16}$

Option 2: $10 \frac{9}{16}$

Option 3: $12 \frac{9}{16}$

Option 4: $8 \frac{9}{16}$

Team Careers360 21st Jan, 2024

Correct Answer: $12 \frac{9}{16}$


Solution : Given: $4(y -\frac{1}{y}) = 13$
Squaring on both sides of the above expression, we get,
$⇒4^2(y -\frac{1}{y})^2 = 13^2$
$⇒16(y^2+\frac{1}{y^2}-2) = 169$
$⇒(y^2+\frac{1}{y^2}) = \frac{169}{16}+2$
$⇒(y^2+\frac{1}{y^2}) = \frac{169+32}{16}$
$⇒(y^2+\frac{1}{y^2}) = \frac{201}{16} = 12 \frac{9}{16}$
Hence, the correct answer is $12 \frac{9}{16}$.
