IBPS SO Prelims Exam Model Paper 6

Given:
Amount invested by Aditya = Rs. 21000
The time period for which Aditya invested = 6 months
Profit % of Aditya = 60% of the total profit
Concept used:
Profit (Investment × Time)
Calculation:
Let the amount invested per month by Shifa be ‘x’
∴ Total amount invested in 12 months be 12x
Amount invested by Aditya = Rs. 21000
∴ Total amount invested by Aditya in 6 months = Rs. 21000 × 6
⇒ Total amount invested by Aditya in 6 months = Rs. 1,26,000
Now,
Profit % of Aditya = 60%
∴ Profit % of Shifa = (100 – 60) %
⇒ Profit % of Shifa = 40%
Now, Ratio of Their Profit = 60 : 40
⇒ Ratio of their profit = 3 : 2
Now,

Total‌amount‌of‌Aditya

Total‌amount‌of‌Shifa

= 3/2
⇒

126,000

12x

=

3

2

⇒ 6x = 42,000
⇒ x = 7000
∴ the amount invested by Shifa per month = Rs. 7000
