Question

Twenty percent of Sanju's annual salary is equal to seventy-five per cent of Jaya’s annual salary. Jaya’s monthly salary is 60% of Vivek’s monthly salary. If Vivek’s annual salary is Rs. 1.44 lacs, what is Sanju's monthly salary?

• A. Rs. 70,000
• B. Rs. 27,000
• C. Rs. 24,000
• D. Rs. 54,000
• E. Rs. 36,000

Answer 1

The correct option is B

Rs. 27,000

Given that Vivek’s annual salary is Rs. 1.44 lacs.Therefore, monthly salary of Vivek = Rs. 12,000.

Also given that Jaya’s monthly salary is 60% of Vivek’s monthly salary. Therefore, Jaya’s monthly salary = 60% of 12000 = Rs. 7200

So, Jaya’s annual salary = 12 $\times$ 7200 = Rs. 86400

And given that 20% of Sanju’s annual salary = 75% of Jaya’s annual salary

So $\frac{1}{5}$ of Sanju’s annual salary$=\frac{75}{100}$ $\times$ 86400

Therefore, Sanju’s annual salary $=\frac{75}{100}$ $\times$ 86400 $\times$ 5 = Rs. 324000

So, Sanju’s monthly salary $=\frac{324000}{12}$ = Rs.27000
