Directions: Study the following information to answer the given Questions: Eight persons are sitting in a round table viz. P, Q, R, S, T, U, V, and W. All are facing inside the table. They all have different ages viz. 8, 10, 15, 11, 12, 13, 23 and 25 but not necessarily in the same order. T is sitting 2nd to the left of P whose age is an odd number. Q is sitting beside the one whose age is not a prime number. There are two persons between R and Q. The person whose age is multiple of 5 is sitting opposite to each other. V’s age is cubic number and sits immediate left of Q. S is not the immediate neighbour of T and Q. R is to the immediate left of T. The sum of ages of W and T is 23. V sits 3rd to the right of T whose age is a prime number. W’s age is the second youngest among all. U’s age is the square number and sits beside the person whose age is a prime number. The sum of the age of R and V is 19. The age of S is 12. The person whose age 10 years is not a neighbor of T. The age of Q is less than the age of P. How many persons have age less than the age of S?

In each of the following questions, two rows of numbers are given. The resultant number in each row is to be worked out separately based on the following rules and the questions below the rows of numbers are to be answered. The operations of numbers progress from the left to the right. Rules: (i) if an odd number is followed by a two-digit even number then they are to be added. (ii) If an odd number is followed by a two-digit odd number then the second number is to be subtracted from the first number. (iii) If an even number is followed by a number which is the perfect square of a number then the second number is to be divided by the first number. (iv) If an even number is followed by a two-digit even number then the first number is to be multiplied by the second number. 19 15 12 15 12 23 16 If the resultant of the second set of numbers is subtracted from the resultant of the first set of numbers, what will be the outcome ? 1) 44 2) 92 3) 29 4) 43 5) None of these

A square piece of cardboard with side 12 cm has a small square of 2 cm cut out from each of the corners. The resulting flaps are turned up to make a box 2 cm deep. The volume of the box is: 12 cm सतह वाले एक वर्गाकार गत्ते के टुकड़े के प्रत्येक कोने से 2 cm छोटे वर्ग काटे जाते है | 2 cm गहरा डिब्बा तैयार करने के लिए परिणामों पट्टियां (resulting flaps) को मोड़ा जाता है| डिब्बे के घनफल का मान क्या है?
