Answer 1

1) A has 100
B has 100
C has 100
D has 100

Now A pays 20 to B
A = 100 - 20 = 80
B = 100 + 20 = 120


Now B pays 10 to C
B = 100 - 10= 110
C = 100 + 10 = 110

C gets 30 from D
D = 100 - 30 = 70
C = 110 + 30 = 140

Finally A has 80 B has 110 C has 140 D has 70
a) C is the richest ✓
b) D is poorest ✓
d) B is richer than D✓

Therefore, Option c is wrong
Option c is your answer


2) 45% = A
55% = B
40% = C

Now 30 read A and B
so only people who read A = 45 - 30 = 15
Only who reads B = 55 - 30 = 25

15 read B and C
B = 25 - 15 = 10
C = 40 - 15 = 25

10 percent read all
A = 15 - 10 = 5
B = 10 - 10 = 0
C = 25 - 10 = 15

15 percent only read C 5 percent only read A

I guess your answer is 15 - 5 = 10

I am not sure

3) First water content = 1 - 1/3 = 2/3
Second water content = 1 - 1/4 = 3/4

Mixed together water = 2/3 + 3/4
= 8/12 + 9/12
17/12

Mixed together milk = 1/3 + 1/4
= 4/12 + 3/12 = 7/12

Hence ratio = 7/12 : 17/12
= 7:17



Hope it helps dear friend ☺️✌️✌️
