Answer: The answer is 1,200 students.
Step-by-step explanation:
Well, 3/5 is 60%. So 60% + 15% is 75%. if the rest of the students are English revision then that is 25%. Since 25% is 40 and 25% times 3 is 75% then 40 times 3 would be the answer. The answer is 1,200 students.
A = b+5
ab = 3300
(b+5)b = 3300
b² +5b -3300 = 0 (quadratic formula)
b=55
a=60 (by first relation)
