Detailed Solution

Given that seema types 582 words during half an hour.
We need to find the number of words would she type in 10 minutes.
We know that,1 hour = 60 mins and half hour = 30 mins.
Assume that word typed in 10 minutes are y.
Understand that words typed are in direct proportion with the time and hence the ratio of word typed and time taken would be constant.
Equate the ratio of word typed in half an hour and ratio of word typed in 10 minutes and solve.
y10=58230
y=582×1030
y=5823
y=194
Hence, 194 words are typed in 10 minutes.
Hence, the correct option is 1.
