प्र: A container contains 120 lit of Diesel. From this container, 12 lit of Diesel was taken out and replaced by kerosene. This process was further repeated for two times. How much diesel is now there in the container ? 1709 0

उत्तर : 2. "87.48 lit"
व्याख्या :
Answer: B) 87.48 lit Explanation: For these type of problems, Quantity of Diesel remained = q1-pqn Here p = 12 , q = 120 => 1201-121203 = 120 x 0.9 x 0.9 x 0.9 = 87.48 lit.

प्र: What will come in place of the question mark (?) in the following question ? 52.5% of 800 + 30.5% of 2800 = ? + 87.30 1707 0

उत्तर : 4. "1186.70"
व्याख्या :
Answer: D) 1186.70 Explanation: 52.5% of 800 + 30.5% of 2800 = ? + 87.30 420 + 854 - 87.30 = ? 1274 - 87.30 = ? ? = 1186.70

उत्तर : 3. "3:4"
व्याख्या :
Answer: C) 3:4 Explanation:

प्र: 83% of 2350 = ? 1702 0

उत्तर : 4. "1950.50"
व्याख्या :
Answer: D) 1950.50 Explanation: 83% of 2350 = ? 83/100 x 2350 =8.3 x 235 =1950.50

प्र: On dividing a number by 96, we get 271 as quotient and 0 as remainder. On dividing the same number by 95, what will be the remainder ? 1698 0

उत्तर : 4. "81"
व्याख्या :
Answer: D) 81 Explanation: Number = 271 x 96 + 0 = 26016 => 95) 26016 (273 25935 -------- 81 Required number = 81.

प्र: There are 11 True or False questions. How many ways can these be answered ? 1698 0

उत्तर : 4. "2048"
व्याख्या :
Answer: D) 2048 Explanation: Given 11 questions of type True or False Then, Each of these questions can be answered in 2 ways (True or false) Therefore, no. of ways of answering 11 questions = 211 = 2048 ways.

प्र: Manisha went to shop with certain amount, with which she can buy 50 Chacobar or 40 Fivestar. She uses 10% amount for petrol and out of the remaining balance, she purchases 20 Fivestar and some Chacobar. Find the number of Chacobar she can buy? 1697 0

उत्तर : 1. "20"
व्याख्या :
Answer: A) 20 Explanation: Let the total amount be 200 {L.C.M of 40 and 50} Chacobar C.P. = 200/50 = 4 Fivestar C.P = 200/40 = 5 Remaining Money after petrol = [200 - 200×10%] = 180 Remaining money after buying fivestars = [180 - 20×5] = 80 So number of Chacobar she can buy = 80/4 = 20

प्र: One card is drawn from a pack of 52 cards, each of the 52 cards being equally likely to be drawn find the probability the card drawn is red. 1696 0

उत्तर : 2. "1/2"
व्याख्या :
Answer: B) 1/2 Explanation: We know that: When one card is drawn from a pack of 52 cards The numbers of possible outcomes n(s) = 52 We know that there are 26 red cards in the pack of 52 cards⇒ The numbers of favorable outcomes n(E) = 26 Probability of occurrence of an event: P(E)=Number of favorable outcomes/Numeber of possible outcomes=n(E)/n(S) ∴ required probability = 26/52 = 1/2.
