IBPS SO Prelims Exam Model Paper 4

Given:
Vani gave 16% of her pocket money to Saurabh.
Saurabh = 15% on books, 45% on watch
Calculation
Vani gave 16% of her pocket money to Saurabh
⇒ Saurabh's amount = 16% of Vani's amount
From the money he received, he spent 15% on buying books and 45% on buying a watch
⇒ Remaining = 100 - (15% + 45%) = 40%
Accordingly,
40% of amount = 3200
⇒ (

40

100

) × Saurabh's amount = 3200
⇒ Saurabh's amount = 3200 ×

100

40

⇒ Saurabh’s Total amount = 8000
Saurabh's amount = 16% of Vani's amount
⇒ 8000 = (

16

100

) × Vani
⇒ Vani = 50000
∴ Initially Vani’s pocket money was Rs 50000
