2) If a number is divided into three parts which are in the ratio 1:1:2, then what percentage of the total value is the sum of the equal parts?
3) A train crosses a stationary pole in 20 secs when it is travelling at 54 km/hr. Find the length of the train (in m)
Answers
Step-by-step explanation:
1.RATIO OF TWO VEHICLES=3:2
TOTAL COST=50000
LET COST OF VECHILES INDIVIDUAL IS X
SUM OF RATIOS=3+2=5
COST OF VEHICLE 1=3/5*50000
=30000
COST OF VEHICLE 2=2/5*50000
=20000
2.SORRY I DONT KNOW THIS ANSWER
3. I THINK THIS IS CORRECT
T=20S
V=54KM/H=54*5/18
=20 M/S
S=VT
S=20*20
=400M
Answer:
The cost of individual vehicle are 30000 and 20000.
Step-by-step explanation:
1) Let the individual cost of two vehicles be 3x and 2x,
the total cost of the two vehicles = ₹50000
3x + 2x = ₹50000
5x = ₹50000
x = ₹50000/5
x = ₹10000
The individual cost of two vehicles are
3x = 3 x 10000 = 30000
2x = 2 x 10000 = 20000
