1. 2,690
2. 2,520
3. 2,500
4. 2,680

Answer 1

Correct Answer - Option 2 : 2,520

Given :

30% spends on groceries

20% of remaining spends on rent and

45% of the remaining spends on children's education

Calculation :

Let the total monthly income be Rs.100 units

⇒ groceries = 30 (now, remaining Rs.70)

⇒ rent = 20% of 70

⇒ rent = 14 units (now,remaining Rs. 70 - 14 = 56)

⇒ children's education = 45% of 56

⇒ children's education = 25.2

⇒Total spending = 30 + 14 + 25.2 = 69.2

⇒ Total monthly savings = 100 - 69.2

⇒ 30.8

according to question,

30.8 units = Rs.5544

⇒ 1 unit = Rs.180

∵ spending on rent is 14 units

∴ Arun spends Rs.2520 on rent
