Answer: D) 8 months Explanation: Let the total Profit be Z.Ramu's profit share is 2/3 of profit (i.e 2Z/3)Ravi's profit is (Z-2Z/3) =Z/3Hence the profit ratio is , Ravi : Ramu = Z/3 : 2Z/3 = 1:2 Let total Capital be Rs.X and Ramu has contributed for Y months.Since Ramu's profit share is 2/3, his invest share will be 2/3 in capital. Ravi's invest for 16 months / Ramu's invest for Y months = Ravi's profit share / Ramu's profit sharei.e. (X/6 x 16) / (2X/3 x Y) = 1/2 Solving the above equation, we get Y = 8.So Ramu's money has been used for 8 months.

Answer: B) 21,14 Explanation: Putting A=1, B=2, C=3,..., M=13,....,X=24,Y=25, Z=26, we have :        JR = J + R2 + 2 = 10 + 18 2 + 2 = 16       CK = C + K2 + 2 =  3 + 112 + 2 = 9       TX = T + X2+ 2 = 20 + 242 + 2 = 24       OS = O + S2 + 2 = 15 + 192 + 2 = 19        So, the missing numbers are :       21 and 14       Hence, the answer is (b).

Answer: A) TRUE Explanation: Yes, a square is a rhombus.

Hence, if the interior angles of a rhombus are all at right angles (90 deg), then it is square.
