प्र: Two boys are playing on a ground. Both the boys are less than 10 years old. Age of the younger boy is equal to the cube root of the product of the age of the two boys. If we place the digit representing the age of the younger boy to the left of the digit representing the age of the elder boy, we get the age of the father of the younger boy. Similarly, we place the digit representing the age of the elder boy to the left of the digit representing the age of the younger boy and divide the figure by 2, we get the age of the mother of the younger boy. The mother of the younger boy is younger than his father by 3 years. Then, what are the ages of elder and younger boys ? 4554 05b5cc73ae4d2b4197774f8ce

उत्तर : 4. "E = 4 & Y = 2"
व्याख्या :
Answer: D) E = 4 & Y = 2 Explanation: Let the the age of the elder boy = E Let the the age of the younger boy = Y Given that Y = cube root of EY => Y3 = EY => E = Y2 .....(1)By the condition of number replacement the age of the father is YE The Mother's age = EY/2 But she is 3 years less than father => EY/2 + 3 = YE2YE = EY + 6 ......(2) Then now from the given options we can identify which satisfies the all the conditions. Here Y =2 and E = 4 satisfies all the conditions.

प्र:Read the passage carefully and give the answer of following questions.
One of the American Navy's greatest losses during World War if was inflicted not by the Japanese, but by the weather. On the evening of 17 December 1944, destroyers, cruisers and aircraft carriers of the Third Fleet Task Force 38 were replenishing stocks of food, fuel and ammunition during a sea rendezvous with support ships when a savage tornado struck the Philippine Sea. One of the commanders said later: 'My ship was riding as though caught in some giant washing machine. We were rolling between heaving clifs of water, caught in so strong a vice of wind and sea that our 50,000 horse- power engines were helpless. It was nine hours before he regained control of his ship, after the fleet had bobbed like helpless shuttlecocks, unable to prevent collisions in the sledge hammer waves.

उत्तर : 3. "35 and 11 years"
व्याख्या :
Answer: C) 35 and 11 years Explanation: Let the age of sushma be x and the age of her son is yThen five years before x-5=5(y-5) ...(1)Five years hence x+5 = 3(y+5)-8 .....(2) By soving (1) & (2), we get5y - 15 = 3y + 7y = 11 => x = 35 Therefore, the age of Sushma = 35 and her son = 11.
