Ahaan, Vihaan and Riyaan run different shops selling wheat. All three of them sold wheat for Rs. 800 per ton in February and Rs. 1200 per ton in March. Their total sales were 25, 28 and 33 metric tons respectively during February-March. But their turnovers (i.e., revenues) were the same for the February-March period (Assume that all the sales are integral metric tons).

Explanation :
Let the sales for January be a, b and c tons respectively for each of them.
∴ Total sales for Jan and Feb for
Ahaan: 800 × a + 1200 × (25 - a) = 30,000 – 400a
Vihaan: 800 × b + 1200 × (28 - b) = 33,600 – 400b
Riyaan: 800 × c + 1200 × (33 - c) = 39,600 – 400c
Total sales is same for all three.
∴ 30,000 – 400a = 33,600 – 400b = 39,600 – 400c
⇒ b - a = 9 or c – b = 15
⇒ b = 9 + a and c = 24 + a
∴ Possible solutions are
∴ 7 cases are possible
Hence, option (d).

Explanation :
Let the Selling Price of a copy A, B and C be 4x, 5x and 6x respectively.
Let the Cost Price of a copy A, B and C be CA, CB and CC respectively.
Let the number of copies of A, B and C sold on that Sunday be a, b and c respectively.
∴ 1.1aCA + 1.2bCB + 1.3cCC = 1.2(aCA + bCB + cCC)
⇒ aCA = cCC
⇒ = > 1
Hence, option (b).

A tradesman, by means of a false balance, defrauds 10% in buying goods and 10% in selling. What % does he gain on his outlay by his dishonesty if he professes to sell the goods at cost price?
- (a)
21.33%
- (b)

Explanation :
Let the CP for tradesman be Rs. 1/gm
Since he defrauds 10%, he will get 110 gms for every 100 gms he pays for.
∴ He buys 110 gms for Rs. 100.
While selling, he gives only 90 gms for every 100 gms.
So, the tradesman will give 110 gms for 110 × 100/90 = Rs. 122.22
∴ Profit % = 22.22%
Hence, option (d).
