What maximum sum of numbers you can pick. 165150 1600843 168132420 165322501 Arithmetic Aptitude 2 Number Divisibility 50 Aptitude & Reasoning MCQs with Answers Discuss itQuestion 2-Explanation: All 3 digit numbers divisible by 3 are : 102, 105, 108, 111, ..., 999. This is an A.P. with first element \'a\' as 102 and difference \'d\' as 3. Let it contains n terms. Then, 102 + (n - 1) x 3 = 999 102 + 3n-3 = 999 3n = 900 or n = 300 Sum of AP = n/2 [2*a + (n-1)*d] Required sum = 300/2[2*102 + 299*3] = 165150. Question 3Which of Following is not divisible from 4 ?546702556824367312467536Arithmetic Aptitude 2 Number Divisibility Discuss itQuestion 3-Explanation: If last 2 digits are divisible by 4, then number is also divisible by 4. In case of 546702 last 2 digits are 02 (x) In case of 556824 last 2 digits are 24 (/) In case of 367312 last 2 digits are 12 (/) In case of 467536 last 2 digits are 36 (/) Question 4What should be the value of * in 985*865, if number is divisible by 9?6540Arithmetic Aptitude 2 Number Divisibility 50 Aptitude & Reasoning MCQs with Answers Discuss itQuestion 4-Explanation: If a number is divisible by 9, the sum of digits is also divisible by 9 9 + 8 + 5 + * + 8 + 6 + 5 = 9x 41 + * = 9x Nearest value of 9x must be 45 41 + * = 45 * = 4Question 5The least perfect square, which is divisible by each of 15, 20 and 36 is: 12008001000900Arithmetic Aptitude 2 Number Divisibility 50 Aptitude & Reasoning MCQs with Answers Discuss itQuestion 5-Explanation: LCM of 15, 20 and 36 is 180 Now 180 = 3 x 3 x 2 x 2 x 5 To make it perfect square, it must be multiplied from 5. So required no. = 32 x 22 x 52 = 900Question 6What should be the value of x in equation (x / √216) = (√96 / x)1213911Arithmetic Aptitude 2 Simplification and Approximation 50 Aptitude & Reasoning MCQs with Answers Discuss itQuestion 6-Explanation: Let (x / √216) = (√96 / x) Then x2 = √(216 x 96) = √(36 x 2 x 3 x 16 x 2 x 3) = √(62 x 42 x 22 x 32) = 6 x 4 x 2 x 3 = 144 Or x = 12 Question 7 Sum of the age of 4 children born at interval of 4 years is 36. What is the age of youngest child? 2 years 3 years 4 years 5 years Arithmetic Aptitude 2 Age 50 Aptitude & Reasoning MCQs with Answers Discuss itQuestion 7-Explanation: Let the ages of children be x, (x+4), (x+8) and (x+12) years. Then x + x + 4 + x + 8 + x +12 = 36 4x + 24 = 36 4x = 12 x = 3 Age of the youngest child = x = 3 yearsQuestion 8A is 5 years older than B who is thrice as old as C. If the total of ages of A, B and C is 40, then how old is C ? 6758Arithmetic Aptitude 2 Age 50 Aptitude & Reasoning MCQs with Answers Discuss itQuestion 8-Explanation: Let C’s age be x years then B’s age be 3x years and A’s age be (3x+5) years Therefore x + 3x + (3x + 5) = 40 7x + 5 = 40 7x = 35 x = 5 1 There are 8 questions to complete.
