The Indian cricket team has to score 360 runs on the last day of a test match in 90 overa, to win the test match. This target is set by Brian Lara after he declared his innings closed at the overnight score of 411 for 7.
The following is the info on batting rates of different batmen:
Assume the run rate of partnership is the weighted average of the individual batting rates of batsmen involved in partnership (on the basis of ratio of the strike each batman gets, I.e. the run rate of a partnership is defined as the weighted average of the run rates of the two batsmen involved weighted by the ratio of the number of balls faced by each batsman).
Runs scored per over in different batting styles is below:
Name Defense Normal Agress
Das. 3. 4. 5
Gupt. 2. 3. 4
DRA. 2. 3. 4
Ten. 4. 6. 8
Lax. 4. 5. 6
Seh 4. 5. 6
Gan. 3. 4. 5.
Kumb. 2. 3. 4
Har. 3. 4. 5
Srin. 3. 4. 5
Yoh. 2. 3. 4
Assume no extras unless stated
Assume strike is equally shared unless otherwise stated.
Question 1:
If the first wicket pair of das and gupt bats for 22 overa and during this partnership Das has started batting normal and turned agress after 15 overs while Gupt started off defense but shifted to bat normal after batting for 20 overs, find the expected score after 22 overs.
