Square root of 8464 92 8464 8100 90 2 92 2 Therefore, Square root of 8464 92 Q. Step 1: in 1728, 8 replaces by 2 (8 3 512) Therefore, unit place digit is 2 Step 2: in 1728, ignore 728 (last 3 digits) We now have 1 Here, 1 1 3 (1 2 3 ) Therefore, tenth place digit is 1 Therefore, Cubeth root of 1728 12 (answer) Q. Square of middle number of given numbers 1 2 11 13 Here, the difference between 11 13 is 2 and the middle number is 12 Therefore, 12 2 1 2 144 1 143 (answer) 15 17 Here, the difference between 15 17 is 2 and the middle number is 16 Therefore, 16 2 1 2 256 1 255 (answer) 24 26 Here, the difference between 24 26 is 2 and the middle number is 25 Therefore, 25 2 1 2 625 1 624 (answer) 2. Square of middle number of given numbers 2 2 11 15 Here, the difference between 11 15 is 4 and the middle number is 13 Therefore, 13 2 2 2 169 4 165 (answer) 17 21 Here, the difference between 17 21 is 4 and the middle number is 19 Therefore, 19 2 2 2 361 4 357 (answer) 60 64 Here, the difference between 60 64 is 4 and the middle number is 62 Therefore, 62 2 2 2 3844 4 3840 (answer) 3. Square of middle number of given numbers 3 2 11 17 Here, the difference between 11 17 is 6 and the middle number is 14 Therefore, 14 2 3 2 196 9 187 (answer) 13 19 Here, the difference between 13 19 is 6 and the middle number is 16 Therefore, 16 2 3 2 256 9 247 (answer) 4. Divisibility by 3: A number is divisible by 3 if the sum of digits in the number is divisible by 3 Example: 2553 Here, 2 5 5 3 15, which is divisible by 3 hence 2553 is divisible by 3 Divisibility by 4: A number is divisible by 4 if its last two digits is divisible by 4 Example: 2652 Here, 52 is divisible by 4, so 2652 is divisible by 4 Divisibility by 5: A number is divisible by 5 if the units digit in number is 0 or 5 Example: 20, 35, 140, 165 etc. Divisibility by 6: A number is divisible by 6 if the number is even and sum of digits is divisible by 3 Example: 4536 4536 is an even number and also sum of digit 4 5 3 6 18 is divisible by 3 Divisibility by 7: To check whether a number is divisible by 7 or not first multiply the units digit of the number by 2 and subtract it from the remaining digits, continue this process. N 2 S n (n1) (n2)2 Sum of cubes of first n- natural numbers S 1 3 2 3 3 3 4 3. P): In Mathematics, an Arithmetic Progression or Arithmetic Sequence is a sequence of numbers such that the difference between the consecutive terms is constant For example, the sequence 5, 8, 11, 14, 17, 20 is an Arithmetic Progression with common difference of 3 The general form of Arithmetic Progression is a, a d, a 2d, a 3d, a 4d. First term a Common ration r Any particular term or n th term a n Sum of first n terms S n a n a rn S n a ( rn ) rn r 1 S n a (1- rn)1-r r Ramanujans Number (1729): It is a very interesting number, it is the smallest number expressible as the sum of two cubes in two different ways 1729 1 3 12 3 9 3 10 3 Practice Problems 1. If the expressions x 809436 809438 be a perfect square, then the value of x is 2. The first term of a Geometric Progression (G.P) is 1. The sum of the third and fifth terms is 90. Find the common ratio of the G.P 3. A number when divided by 56, the remainder is 29. The sum of two numbers is equal to 200 and their difference is 25. If then the value of a 2 331a is. If 1. 5a 0. 04b, then is equal to 7. The number obtained by interchanging the two digits of a two-digit number is lesser than the original number by 54.
