13533/31 = 436 quotient and 17 remainder
436*31=13516
436*32=13547
13533+14=13547
14 is to be added
14
It is 8961 - W*int(8961/W)
Well 924 by 48 give 19 as quotient . 48*19 is 912; 48Γ20 is 960. now 924 + 36 is 960 so 36 is
Add 22 to 1,057,100 .The sum is 1,057,122 .That's 418 x 2,529 .
3924 is divisible by 3 as the digits added together 3+9+2+4=18 is divisible by 3
Nope - For any number to be divisible by three, the sum of the digits added together must ALSO be divisible by three. In this case 1+4=5.
459684/187 give 2458 and 38 as quotient and remainder. Now next possibility 187 *2459 give 459833. 459833-459684 =149 it should be added. 149 is answer
339 + 1 = 340,which is exactly divisible.
3500/42 give 83 quotient,14 remainder next possibility 42*84 =3528. 28 must be added to 3500 then only it will divisible by 42.now check the dividend 3528 with the following divisor 49,56,63 3528/49=72 divisible 3528/56=63 divisible 3528/63=56 divisible So 3528 is divisible by 42,49,63,56 So 28 must be added 28 is the
10056Γ·23 gives 437 as quotient and 5 as remainder. Dividend-remainder= divisor× quotient so 10056-5=23×437 gives 10051.our question is least no should be added to 10056 which is divisible by 23. Check next possibility 23×438 gives 10074. Now 10056+18= 10074. Therefore 18 is the least number should be added to 10056 to get a number divisible by 23
It is 8961 - W*int(8961/W)
It is 20 because 5220/180 = 29
the rule for divisibility by 9 is that the sum of all digits of the number should should be divisible by 9. So, 3+9+0+6+5= 23. To make is divisible by 9, we think of 27 (as the next number divisible by 9) and that means if we add 4 to any digit of the number, it will be divisible. 39069/9=4341
It is: 36 and so 960/48 = 20
403Γ·8 gives 50 as quotient and 3 as remainder. Dividend- remainder=divisor Γquotient 403-3=8*50 which is 400. our value is 403 So increase divisor 8*51=408. 403+5 gives 408. So 5 must be added to 403 to get a no divisible by 8.
Well 924 by 48 give 19 as quotient . 48*19 is 912; 48Γ20 is 960. now 924 + 36 is 960 so 36 is
8 added to 4952 makes it divisible by 32
25219/46 gives 548 quotient 11as remainder. Next possibility is 46*549 =25254. Now compare 25254 and 25219 their difference is 35. So 35 must be added to 25219. Ans 35
