ATQ, Let's denote the amount as 'A'. Given, 40% of A is Rs 55. So, 0.40 × A = Rs.55 Now, to find 160% of the same amount: 160% × A = 1.60 × A Let's solve for A using the information provided: 0.40 × A = Rs.55 A = (Rs.55/0.40) Now, substitute this value into (1.60 × A) to find 160% of the amount: 1.60 × Rs.137.50 = Rs220 Therefore, 160% of the amount is Rs 220.
