Two places A and B are 120 km apart on a highway. A car starts from A and another from B at the same time if the car move in the same direction at different speeds they meet in 6 hours if they travel towards Each Other they need in 1 hour 12 minutes find the speed of the two cars.​

Answer»

Answer:

Let,

speed of car at "a" be x kmph 

speed of car at "b" be y kmph

dis covered by car at "a" in 6 hours = 6x

dis covered by car at "b" in 6 hours = 6y

Since they are travelling in same direction, sign shouble be negative

6x - 6y = 120

x - y = 20 ------------ (1)

1HR 12 min = 1 12/60 = 72/60 = 6/5 hr

Since they are travelling in opposite DIRECTIONS, sign should be positive.

(6/5)x + (6/5)y = 120

6x + 6y = 120×5

6x + 6y = 20×5

x + y = 100 ------------ (2)

Adding (1) and (2)

we get 2x = 120 

x = 60

Putting x = 60 in (2) 

we get y = 40 

Therefore,speeds cars are 60 km/h & 40 km/h.

I have collected coins in a piggy bank. The day I opened it I found I had 3 times as many 50 paise coins asone rupee coins. The total amount in the piggy bank is 150. How many coins of each kind are there?

Answer»

LET US assume that the number of COINS of 1 RUPEE are x

therefore coins of 50 paisa are 3x

amount of 1 rupee coin = 1×x=100x paisa

amount of 50 paisa coins=50×3x=150 paisa

100x+150x=4500

250x=4500

x=18

(a) Prove if P(n,r) = P(n-1,r) + r.P(n-1, r-1)​

Answer»

We have to PROVE that,

^n\!P_r\ =\ ^{n-1}\!P_r\ +\ r\cdot\ ^{n-1}\!P_{r-1}

\cline{1-}

First we write the three PERMUTATIONS in fractional form.

^n\!P_r=\dfrac{n!}{(n-r)!}

^{n-1}\!P_r=\dfrac{(n-1)!}{(n-1-r)!}=\dfrac{(n-1)!}{(n-r-1)!}

^{n-1}\!P_{r-1}=\dfrac{(n-1)!}{(n-1-r+1)!}=\dfrac{(n-1)!}{(n-r)!}

Since RHS has more TERMS, LET me take the RHS first. So,

\begin{aligned}&\textsf{RHS}\\ \\ \Longrightarrow\ \ &^{n-1}\!P_r+r\cdot\ ^{n-1}\!P_{r-1}\\ \\ \Longrightarrow\ \ &\frac{(n-1)!}{(n-r-1)!}+r\cdot \frac{(n-1)!}{(n-r)!}\\ \\ \Longrightarrow\ \ &\frac{(n-1)!}{(n-r-1)!}+\frac{r(n-1)!}{(n-r-1)!(n-r)}\\ \\ \Longrightarrow\ \ &\frac{(n-1)!}{(n-r-1)!}\left(1+\frac{r}{n-r}\right)\\ \\ \Longrightarrow\ \ &\frac{(n-1)!}{(n-r-1)!}\cdot \frac{n-r+r}{n-r}\\ \\ \Longrightarrow\ \ &\frac{(n-1)!}{(n-r-1)!}\cdot\frac{n}{n-r}\end{aligned}

\Longrightarrow\ \ \dfrac{(n-1)!\ n}{(n-r-1)!\ (n-r)}\\ \\ \\ \Longrightarrow\ \ \dfrac{n!}{(n-r)!}\\ \\ \\ \Longrightarrow\ \ ^n\!P_r\\ \\ \\ \Longrightarrow\ \ \textsf{LHS}

sum of three numbers is 98 full stop ratio of first and second numbers is 223 and that of second and third is 528 full stop what is second number​

Answer»

ANSWER:

LET the second NUMBER be x.

Given: First number / second number = 2/3

=> First number =2/3 × Second number = 2x/3.

Again, second number / THIRD number = 5/8

=> Third number = 8/5 × Second number = 8x/5

Now,Sum = 98

=> 2x/3 + x + 8x/5 =98

=> (10x+15x+24x)/ 15 =98

=> 49x/15 = 98 => x=98×15/49 =30.

So,Second number =30.Ans.
