Option 4: INR 350

Team Careers360 12th Jan, 2024

Correct Answer: INR 300


Solution : LCM of 10. 12 and 15 is 60
Total work = 60
Efficiency of J1 = $\frac{60}{10}=6$
Efficiency of J2 = $\frac{60}{12}=5$
Efficiency of J3 = $\frac{60}{15}=4$
The ratio of their efficiencies = 6 : 5 : 4
Amount received = INR 2250
Share of J1 = $\frac{2250}{15}\times6=900$
Share of J2 = $\frac{2250}{15}\times5=750$
Share of J3 = $\frac{2250}{15}\times4=600$
The difference in the shares of Jand J3 = 900 – 600 = 300
Hence, the correct answer is INR 300.

Option 4: 4

Team Careers360 16th Jan, 2024

Correct Answer: 4


Solution : Given: The sum of two positive numbers is 240 and their HCF is 15.
Let $x$ and $y$ be two coprime then the numbers are $15x$ and $15y$.
According to the question,
$15x+15y=240$
⇒ $x+y=16$
The number of pairs of numbers satisfying the given condition = 4 i.e. (1, 15), (3, 13), (5, 11), and (7, 9).
Hence, the correct answer is 4.
