abhinaw kumar  (8 years ago) Best Solution

for c=40 ,F=((9/5) *40)+32=104
c=45 ,f=(9*9)+32=113
c=50 ,f=(9*10)+32=122
c=55 ,f=(9*11)+32=131
c=60 ,f=(9*12)+32=140
c=65 ,f=(9*13)+32=149
c=70 ,f=(9*14)+32=158
c=75 ,f=(9*15)+32=167
c=80 ,f=(9*16)+32=176
c=85 ,f=(9*17)+32=185
c=90 ,f=(9*18)+32=194
so ans is 11.

Kundan singh  (8 years ago)

sorry bhai log ans will be 11 logic 9/5*30+32=76 less then 100 so neglect 30 9/5*40+32=104 then 45 50 55 60 65 70 75 80 85 90 and 95 not possible because its exceeds 200

prachi  (8 years ago)

the answer will be 11.because putting the value of c from 40 to 90,the values of F are lying between 100 to 200

As F needs to be integer, then C should be a multiple of 5. First integer value of F for C = 5 is 41, next value for C =10 is 50 and so on.
The values of F are in A.P with common difference of 9. They are in the format of 41 + 9n.
The first value of F which is greater than 100 is for n = 7 which is 104.
The last value of F which is less than 200 is for n = 17, which is 194.
Total values are ((194−104)/9)+1 = 11
