C P = 14630 × 77/100 = Rs. 19000

1. 1;

Sum of the three number = 30 × 3 = 90

1. 4;

Let the length and breadth be 3x and 2x respectively.

2(3x + 2x)/(3x * 2x) = 5/9

10x/6x^2 = 5/9

x = 3

Length = 3 * 3 = 9m

1. 2;

Salary of supervisor = 9000 × 16 – 8600 × 15

= 1,44,000 – 1,29,000 = Rs. 15000

Speed of train = 330/6 = 55 m/sec

Required time = (330 + 165)/55 = 9 sec

1. 4

Let income be Rs. x

Expenditure = Rs. 75/100x

Saving = Rs. 25/100x

Now, income = Rs. 120/100x

Expenditure = Rs. 75/100 * 116/100

Savingsn = 120x/100 – (75 * 116)x/10000

= (120/100 – 87/100)x

= 33/100x

Saving increased = (33x – 25x)/25x * 100 = 32%
