2) 1:2:3
3) 1:1:3
4) 1:1:2
5) 1:1:1

Only Answer 3 will satisfy the answer. 2) Total Paid = 3*2662 = 7986 X + X*10/100 = 7986 1.1X = 7986 => X = 7260 SVP Joined: 29 Aug 2007 Posts: 2476 Followers: 70 Kudos [?]: 774 [0], given: 19 Re: Mixture/S.I.

with the ratio of 2:3:4, the actual sum is (2x10 + 3x12 + 4x16) = 120. so not suff.

2) if price of the mixture is $14 and the tees are in the ratio of 1:2:3, then sum of the mixture must be 84. lets check whether the sum is 84 or not. with the ratio of 1:2:3, the actual sum is (1x10 + 2x12 + 3x16) = 82. so not suff. 3) similarly the sum must be 70. actual sum = 10x1 + 12x1 + 16x3 = 70. bingo... 4) cannot be 5) cannot be so C.

Please explain the procedure for both.

assuming no advance payment, the loan amt = 2662/1.1 + 266/(1.1)^2 + 266/(1.1)^2 = 2420 + 2200 + 2000 = 6620
