Answer:

Step-by-step explanation:
Money proportion of A, B, C and D are 5:2:4:3.
So, let the money shares received by A, B, C and D be 5x, 2x, 4x and 3x rupees respectively.
It is given that:
C gets ₹1000 more than D







Multiply "7" by each term inside the parentheses.
7(x-20) = 7x-140
answer: 7x-140
Et y represent the number of students in the group who are not members. You can write an expression for y in terms of x from the information given. What do you know? The total number of students = 19 x + y = 19 which gives you y = 19 - x OR you also know the total cost is 209 and you can use that and the cost of the two types of tickets to obtain an expression for y in terms of x.
Most of the information's necessary for solving this problem is already given in the question.
Let us assume the number to be = x
Then
25% * x = 19
(25/100) * x = 19
x/4 = 19
x = 19 * 4
= 76
So the unknown number is 76. I hope there is no complexity in the method described above and also the procedure is clear enough for you to understand. You can use this method for solving similar type of problems in future without requiring any additional help from outside.
