Answer & Explanation

Total students are 40 × 15 = 600
So, 18 x 16 + (12 + 14) = 456
Left student is 10 and their average is =600-456= 144÷ 10=14.4

The interest in 2 years is 594.5 which is 10.25% of 5800. Hence the rate of interest is 5% p.a.

Upstream speed = 5 km/hr
Downstream speed = 15 km/hr
Speed of boat in still water = (5 + 15)/2 = 10 km/hr
Required time = 90/10 = 9 hrs

Let the rate of interest is=x
(X * 5000 * 2)/100 + (3000 * 4 * x)/100 = 2200
x = 10%

Let Car A takes t hrs to reach the place
Distance is same,
35 t = 55(t – 7/2)
T = 77/8
Distance = 35 * 77/8 = 336.87 km

Let the number be X and Y
Then 6y – x = 71 and 7x + y = 62
Solving the equation
X = 7, y = 13

7.(2) C.I. = 85000 × (19.1016/100)
= Rs 16236.36 Approx.

8.(3) Difference of time = 5000/60 − 5000/(60 * 1.15)
= 5000/60 − 5000/69
= 83.33 – 72.46
= 10 min (Approx.)

3*B’s daily work= (A+C)’s daily work
4*B’s daily work = (A+B+C)’s daily work = 1/20
B’s daily work = 1/80
2*C’s daily work = (A+B)’s daily work
3*C’s daily work = (A+B+C)’s daily work = 1/20
C’s daily work= 1/60
A’s daily work= 1/20 – (1/80 + 1/60) = 1/48
A can finish the work in 48 days.

Let the side of park be=’x’
Area of path= 2{(x + 10)5 + 5x}
x = (850 – 50)/10 = 80m
Area =(80)^2=6400 sq.m
