The following question has three statements. Study the question and the statements and decide which of the statement(s) is necessary to answer the question. A man makes a payment in cash using Rs. 2000, Rs. 500 and Rs. 100 notes. Find the amount paid by him. I) The number of notes is in the ratio 6 ∶ 3 ∶ 2 respectively. II) He paid Rs. 4500 in terms of Rs. 500 notes. III) He paid Rs. 600 in terms of Rs. 100 notes.?

Option 1 : I and either II or III

Considering statement I,

Let the no. of notes be ‘6x’, ‘3x’ and ‘2x’ respectively

Considering statement II,

No. of Rs. 500 notes = 4500/500 = 9

Considering statements I and II,

⇒ 3x = 9

⇒ x = 3

No. of Rs. 2000 notes = 6(3) = 18

No. of Rs. 100 notes = 2(3) = 6

⇒ Total amount = (2000 × 18) + (500 × 9) + (100 × 6) = Rs. 41100

Considering statement III,

No. of Rs. 100 notes = 600/100 = 6

Considering statements I and III,

⇒ 2x = 6

⇒ x = 3

No. of Rs. 2000 notes = 6(3) = 18

No. of Rs. 500 notes = 3(3) = 9

⇒ Total amount = (2000 × 18) + (500 × 9) + (100 × 6) = Rs. 41100
