Answer: C) 9 Explanation: The given expression can be simplified as 6 ÷ 2 (1 + 2) The expression can be simplified further by the order of operations, using BODMAS rule.   First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction.   Now, the expression becomes 6 ÷ 2 (3)   According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3. 6 ÷ 2 × 3 = 3 × 3 = 9 But not  6÷2×3 = 6 ÷ 6 = 1     Hence, 6 ÷ 2 (1 + 2) = 9.

Answer: D) Rs. 656.25 Explanation: Assume Hebah has Rs. M Since 25% more money at Poonam => Money at Poonam = M + (25% of M) => Money at Poonam = M + 0.25M = Rs. 1.25M Money with Navaneet is thrice the money with Poonam, => Money at Navaneet = 3(1.25M) = Rs. 3.75M Now, sum of all Money = (M + 1.25M + 3.75M) = Rs. 6M But given the average of the money is Rs. 350 => 6M/3 = 350 => 2M = 350 => M = 350/2 = Rs. 175 => Amount of money Navaneet has = Rs. 3.75M = 3.75 x 175 = Rs. 656.25.

Answer: D) Rs. 40 Explanation: Let the cost price of the item = Rs. 50 Sold at 10% loss => for Rs. 50 loss  S.P = Rs. 45 From the  given data, 25/2 % gain if it is sold at Rs. 9 more 56.25 - 45 = 9 => 11.25 = 9 => 22.5 = 18 => 45 = 36 => 50 = ? => C.P = 50 x 3645 = 40   Hence, the Cost price of the item = Rs. 40.
