If p/q =4/5, then the value of 25/7 + {(2q - p) / (2q + p)} is ? | [
"3",
"34",
"2",
"4"
] | D | Answer
Given Exp. = 25/ 7 + {(2q - p) / (2q + p)}
Dividing numerator as well as denominator by q,
Exp = 25/7 + {2-p/q) / (2 + p/q)}
= 25/7 + {(2 - 4/5) / (2 + 4/5)}
= 25/7 + 6/14
= 25/7 + 3/7
=28/7
=4

The average mark of the students of a class in a particular exam is 65. If 5 students whose average mark in that exam is 20 are excluded, the average mark of the remaining will be 90. Find the number of students who wrote the exam. | [
"35",
"14",
"25",
