(2) d > 20 Are You Up For the Challenge: 700 Level QuestionsOkay, the solution would be If a positive integer m is divided by d, the remainder is 5 MEANS m=dq+5 (1) When \(\frac{m}{3}\) is divided by d, the remainder is 15. So, \(\frac{m}{3}=xd+15.....m=3xd+45\) equating values of m....\(dq+5=3xd+45.......d(q3x)=40\). All of the variables are integers, so d and q3x must be factors of 40, and should have their product as 40. So, d can be any factor of 40 but greater than 15 as we know remainder in one case is 15..Thus d can be 20 or 40 (2) d > 20 d could be anything Combined d cannot be 20, so d=40C

giving a try given m=d*a+5 find d #1 m/3= d*a+15 m=3da+45 da+5=3da+45 da= 20 insufficient #2 d>20 insufficient from 1 &2 da=20 d=60 , a =1/3 ; d= 80 ; a= 1/4 insufficient IMO E Bunuel wrote: If a positive integer m is divided by d, the remainder is 5.

How da can be same for both the expressions. m= da+5 m/3 = da+15 Could you explain this?

IMHO, the question implicitly asks to solve a system of (max) 3 equations in 4 variables. Impossibile by definition.

Unsure of my answer but here goes my reasoning.
Question statement analysis gives
m = kd + 5 where k is an integer greater than or equal to 0. Since divisor is alway greater than the remainder, d > 5.
Statement 1 analysis: (m/3)/d = qd + 15
Dividing "m/3" by d is same as multiplying m/3 by 1/d. Thus the statement tells us that "m" divided by "3d" gives a remainder of 15. Again, since divisor is greater than the remainder, the above statement implies 3d>15 which means d>5.
We already knew this from the question statement analysis. Thus, statement 1 is insufficient.
Statement 2 analysis:
D>20
No info on m or d hence insufficient.
Combining statement 1 & 2 gives us no new information about either m or the range of d except that d>20. Thus we can deduce no concrete value of d. Insufficient.
The answer is E

The answer is E You are wrong in the highlighted portion.. say m=45 and d=20.. 45 divided by 20 gives 5 as remainder Now 45/3 or 15 divided by 20 will give remainder as 15. BUT m divided by 3d, that is 45 divided by 3*20 or 60 will give 45 as remainder. so m/3 divided by d and m divided by 3d are different when you are checking the remainders

m/d = R(5 ) means d>5 and m = d.x + 5 , where x is any integer 1. let m/3 be y > y = d.p + 15 where p is any integer . Also , note that d>15 otherwise we cant generate remainder of 15. substitute from stem the value of m > dx + 5 = 3dp + 45 d = 40 / ( x 3p ) Now lets find some values of d so that we can prove this statement insufficient. x = 4 p = 1 so, d = 40 x = 5 p= 1 so, d = 20 Hence , insufficient B> insufficient Combined d = 40 only Sufficient
