प्र: If it is possible to make a number which is the square of a two-digit odd number using the second, the fourth and the sixth digits of the number 93217648 and using each only once, which of the following is that two-digit odd number? 1822 0

उत्तर : 2. "19"
व्याख्या :
Answer: B) 19 Explanation: Second, fourth and the sixth digits of the number are 3, 1 and 6. Using these digits only once we can make 361, which is a perfect square number. Hence, our answer is 19 x 19 = 361

प्र: If y/(x - z) = (y + x)/z = x/y then find z : y : x ? 1822 0

उत्तर : 2. "3:2:4"
व्याख्या :
Answer: B) 3:2:4 Explanation: Given, y/(x - z) = (y + x)/z = x/yyz = xy + x2 - yz - xz ....(1)Also xy = yx-z ⇒x2 -xz = y2 ....(2)Using (1) and (2), we get yz = xy - yz + y22yz = xy + y22z = x + y Only option (B) satisfies the equation.

प्र: The number of ways in which six boys and six girls can be seated in a row for a photograph so that no two girls sit together is ? 1821 0

उत्तर : 3. "6! x ⁷P₆"
व्याख्या :
Answer: C) 6! x ⁷P₆ Explanation: We can initially arrange the six boys in 6! ways.Having done this, now three are seven places and six girls to be arranged. This can be done in ⁷P₆ ways. Hence required number of ways = 6! x ⁷P₆

प्र: Express 3/8 and 1/10 as a Decimals? 1820 0

उत्तर : 4. "0.375 & 0.1"
व्याख्या :
Answer: D) 0.375 & 0.1 Explanation: 3/8 as a Decimal : In this we should convert the denominator into 10, 100, 1000, 10000, 100000,... to make it simple. Now to make 8 into 1000, we multiply numerator and denominator with 125 => 3 x 1258 x 125 = 3751000 = 0.375 1/10 as a Decimal : 1 divided into 10 parts of each 0.1. Therefore, 3/8 = 0.375 and 1/10 = 0.1 in decimals.

प्र: Friction can be reduced by changing from 1820 0
