OA = 25Beaker A and beaker B contain methanol, ethanol and phenyl in the ratio 1:3:2 and 2:1:5 respectively. Some parts of the solutions from beaker A and beaker B are thoroughly mixed and put into another beaker C. Which of the following cannot be the ratio of methanol, phenyl and ethanol in beaker C? 10 :23 :15 7 :15 :16 6 :13 :13 9 :20 :18 PS: sab phodu log padhar chuke hain

Let S be the sum of an arithmetic series. The arithmetic mean of every two consecutive terms and every three consecutive terms of S form the consecutive terms of series S1 and S2 respectively. If the sum of all the terms in series S1 and in series S2 are 1375 and 690 respectively, then find the sum of all the terms in series S.
From 4 gentleman and 4 ladies a committee of 5 is to be formed which consist of a president,vice-president and three secretaries.What will be the number of ways of selecting the commitee with atleast 3 women such that atleast one woman hols the post of president or vice-president?420610256512I'm having trouble with this one.
Case 1: 2M + 3F
Ways if 1 woman holds VP/P = 4C3*3C1*4C2*2*2 = 288
If 2 women hold P/VP position = 4C3*3C1*4C2*2 = 144
A went on a tour. He visited a total of 8 cities. In each city he spent Rs.2 less than half the amount he had with him. He spent Rs.100 in the last city he visited. Find the amount he had initially (in Rs.)?

A triangle ABC has 2 points marked on side BC, 5 points marked on side CA and 3 points marked on side AB. None of these marked points is coincident with the vertices of the triangle ABC. All possible triangles are constructed taking any three of these points and the points A, B, C as the vertices. How many new triangles have at least one vertex common with the triangle ABC?
