A number when divided by D leavs a remainder of 8 and when divided by 3D leavs a remainder of 21. What is the remainder left, when twice the number is divided by 3D?
Answer:
Ans: 3
When the number is divided by 3D we got 21. Means the number itself is 21 and 3D >21.
when 21/D, remainder is 8.
So D = 21-8 =13.
now (21*2)/(13*3), Remainder is 3.
