Let the number of Kajubarfis, Gulabjamuns and Sandeshs be k,g and s

Total number of pieces should be 100
=> k + g + s = 100 ---(1)

Net worth of all sweets to be bought is Rs 100
=> 10k + 3g + 0.5s =100
=> 20k + 6g + s = 200 ---(2)
now
(2) – (1) => 19k + 5g = 100
Here two terms are added to get 100. Second term 5g is a multiple of 5.
The only possible value of k is 5
For this value of k, we get g = 1

so no.of gulabjamun is 1
