Solution:
1). Total time taken = (160/64) + (160/80) = 9/2 hrs.
Avg Speed – 320  × (2/9) km/hr = 71.11km/hr

2). Present age of Roshan – x
Present age of Roshan’s father = 4x
Five years ago,
Roshan’s father age = 7 * Ravi’s age
4x – 5 = 7(x – 5)
x = 10
Present age of Roshan’s father = 4x = 40 years.

3). 5x + 3y = z (Total Income)
x + y = 6600 -(1)
5x= 2(3y)
5x – 6y = 0 -(2)
By solving (1) and (2) we get, x = 3600 so y = 3000
(3600*5*1)/100 + (3000*3*1)/100 = 180 + 90 = 270

4). R1 =5x R2=4x T1=T2=1/2 yr
[P1*5x*(1/2)]/100 = [P2*4x*(1/2)]/100
P1:P2 = 4:5

5). Five years ago,
x – 5/y – 5 = 4/1
x – 4y = – 15 —-(i)
After 10 years,
x + 10/y + 10 = 2/1
x – 2y = 10 —–(ii)
From eqn (i) and (ii) => x = 35, y = 12.5

6).  Required percentage mark = [120/(90 + 110 + 100 + 120 + 60 )]* 100
=  (120 / 460)* 100 = 26%

7). New marks of T in physics = (114/100)* 50 = 57
T’s new percentage =  (57/140)* 100 =  41

8). Marks obtained by T in both subjects together is more than the marks obtained by R in Physics.

9).  Required ratio = 130 + 70 : 50 + 60
= 200 : 110 =  20: 11

10). Required ratio = 110 + 120 : 130 + 80   = 230 : 210 = 23 : 21
