The ratio of number of students in 2017 to that of in 2018 is likely to be 4 : 7 and the percentage share of students who will be graduated in finance is likely to increase by 9% then how many more students will be graduated in finance stream?

6.489 lakhs

2.772 lakhs

9.261 lakhs

11.993 lakhs

None of these

Explanation:

Number of students in 2017: Number of students in 2018 = 4 : 7
Assume, number of students in 2017 = 4x and, the number of students in 2018 = 7x
According to the question, number of students in 2017 = 4x = 28 lakhs
So, the value of x = 7 lakhs
Percentage share of students who graduated in Finance stream in 2017 = 9.9% = 9.9% of 28 = 2.772 lakhs
the number of students in 2018 = 7x = 7 × 7 = 49 lakhs
according to the question, the percentage share of students who will be graduated in finance is likely to increase by 9% = (9 + 9.9) % = 18.9%
In 2018, The number of students, who graduated in finance stream = 18.9% of 49 = 9.261 lakhs
Number of more students who will be graduated in finance stream in 2018 = (9.261 – 2.772) lakhs = 6.489 lakhs

Hence, option 1st is correct.
