Question : The average of 25 results is 20. The average of the first 12 results is 15 and that of the last 12 results is 18. Then, the 13th result is:
Option 1: 100
Option 2: 101
Option 3: 104
Option 4: 103
Correct Answer: 104
Solution : Given: The average of 25 results is 20. The average of the first 12 results is 15 and that of the last 12 results is 18. The sum of 25 result = (25 × 20) = 500 The sum of the first 12 results =
Question : Let the HCF of m and n be "a" and let n = ab, LCM of m and n is given by:
Option 1: bm
Option 2: am
Option 3: ab
Option 4: mn
Correct Answer: bm
Solution : Given: HCF = a n = ab We know that, The product of the two numbers = HCF × LCM ⇒ m × n = HCF × LCM Putting the values, we get: ⇒ m × ab = a × LCM Thus, LCM = bm
Question : Directions: Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g., 13 – operations on 13 such as adding /subtracting /multiplying, etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 8 – 72
Option 2: 11 – 143
Option 3: 7 – 63
Option 4: 9 – 99
Correct Answer: 8 – 72
Solution : Let's check the options – First option: 8 – 72; 82 = 64; 64 + 8 × 2 = 64 + 16 = 80 ≠ 72 Second option: 11 – 143; 112 = 121; 121 + 11 × 2 = 121
