First Faulty Phones=1200*(2 1/3%)==1200*7/3*100=28
Defective phones==1200*13/3*100=52

So total defective and faulty phones are 52+28=80
Therefore non defective and non-faulty phones are 1200-(52+28)=1120

A wallet contains 200 notes made up of Rs.100, Rs.50 and Rs.20 notes and their values are in the ratio 1:2:3 then find the values and notes of each type?

Reply Like? Yes | No

(10 years ago)

1000, 2000, 3000
If number of notes of 100, 50 & 20 are x,y, & z respectively, then
x+y+z= 200 ---(i) &
100x/50y= 1/2 ---(ii) &
50y/20z =2/3 ---(iii)
From (ii) & (iii) y=4x & 15y=4z, Substituting in (i), we get x=10, y=40, z=150
So values of each type of notes are (100*10=1000) , (50*40=2000) & (20*150=3000)

D. 8/15
4 days work of A & B= 4[(1/15) +(1/20)]=7/15
So the fraction of work left= 1-(7/15)= 8/15

c) 120 km/hr
If speed of a car=x km/hr, then speed of a train=(150/100)*x=1.5x km/hr
Time taken(in hour) by a car to cover 75 Km.= 75/x &
Time taken(in hour) by a train to cover 75 Km.= [75/(1.5x)] + (12.5/60)
As both car & train reach at the same time, both these times are same
So, 75/x = [75/(1.5x)] + (12.5/60)
On solving, x=120

If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:

A. 50 km B. 56 km
C. 70 km D. 80 km

A. 50 Km.
If time taken =t, then distance covered @14 km/hr=14t and @10 Km/hr= 10t
Given, 14t -10t =20, t=5 hr.
So the actual distance travelled =5*10 =50 Km.

A. 4 years
Sum of the ages of the children= x+(x+3)+(x+6)+(x+9)+(x+12)=50, x=4
So the ages are 4,7,10,13,16
