Read Solution (Total 2)
-
- we can find the number by reverse process as.
reminder 7 and Divisor 8 no. is 8+7 = 15(15 divided by 8 reminder will be 7)
now number which divide by 5 and leaves reminder 4 with Quotient 15 is
(15*5)+4 = 79
same (79*3)+1 = 238.
now 238/8 = 29 reminder 6
29/5 = 5 reminder 4
5/3 = 1 reminder 2 - 10 years agoHelpfull: Yes(0) No(2)
- A number when successively divided by 3,5,8 leaving remainders 1,4,7 can be written as 3(5(8k+7)+4)+1
=>120k+118
when this number is dived by 8 i.e (120k+118)/8=15k+14 remainder 6
(15k+14)/5=3k+2 remainder 4
(3k+2)/3=k remainder 2
And D) 6,4,2
