9) A car normally covers a distance of 360 km at a speed of 45 km/hr. Due to some mechanical failure it halted in two places for different time periods in the ratio 3:5 and its average speed reduced to 30 km/hr. How long the car stopped at first place?

a) 1 hour

b) 3.5 hours

c) 2 hours

d) 1.5 hours

10)  The average of 15 consecutive natural numbers starting from 333 to 361 is x. Find the average if 4 more consecutive natural numbers are added before 333.

a) 347

b) 345

c) 343

d) 351

Answers :

1). Answer:  a)

Let the estimated time= t, distance = x

S=60 kmph

S1=?, S2=?

X/t=60—-(i)

Sub (i) in (ii)

(2x/3)/(4t/5)= (10/12) (x/t)——–(ii)

S1=10/12 x60=50kmph

Remaining distance= x(1-2/3)= x/3

S2=(x/3)/(t/5)——(iii)

Sub (i) in (iii)

S2=5x/3t = 5/3* 60 =100 kmph

The new speed by which he covers the remaining distance on time = 100kmph

2). Answer: c)

Investment of B= 2500/4×5=3125

Profit ratio of A: B = (2500×3) + (2000×2): (3125x 3)+ (3625×2)
= (7500+4000) : (9375+7250)
= 11500 : 16725

= 92:133

3). Answer: a)

The line segment joining midpoint of a side to the vertex opposite to the side is called median. A median bisects area of the triangle intwo equal parts.

4). Answer: a)

Let the four numbers be a, b, c and d respectively.

If all the 4 numbers are even, sum = even

If 1 number is odd and 3 numbers are even, then the sum = odd

5). Answer : d)

Express the given number as prime factors.

3780= 22x 33x5x7

Total number of factors = (2+1) (3+1) (1+1) (1+1) = 3x4x2x2 = 48

No. of ways= 48/2=24

6). Answer: c)

7). Answer: d)

Number of triangles= 1+2+3+4 = 10

8). Answer: a)

Let a=c=2 and b=d=3

Substitute the value in (ab+cd)2

=144

Substitute the value in given options and find which of the equation value is equal to 144.

Option a) satisfies the condition

9). Answer: d)

Original time = 360/45 = 8 hours

Time taken if the avg. speed is 30 km/hr = 360/30 = 12 hours

Car halted for 4 hrs in the ratio 3:5

Halted Time at the first place=   4/8*3=1.5 hrs

10). Answer: b)

Average of numbers from 333 to 361= (333+361)/2=347

Average of all natural numbers if 4 numbers are added before 333= 347-2=345
