Find amount on 8000Rs @ 5%per annum for 3 years compounded yearly?​

Answer»

Answer:

PRINCIPAL for the first YEAR = Rs.8000, Rate = 5% per annum, T = 1 year

INTEREST for the first year = =100P×R×T=Rs.[1008000×5×1]=Rs.400

∴ Amount at the end of the first year = Rs. (8000 + 400) = Rs. 8400

Now principal for the second year = Rs.8400

 Interest for the second year = 100P×R×T=Rs.[1008400×5×1]=Rs.420

∴ Amount at the end of the second year = Rs. (8400 + 420) =Rs.8820

Interest for the third year = 100P×R×T=Rs.1008820×5×1=Rs.441

∴ Amount at the end of the third year = Rs.(8820 + 441) = Rs. 9261

Now we know that total C.I. = Amount - Principal = Rs. (9261 - 8000) = Rs. 1261 

we can also FIND the C.I. as follows

Total C.I. = Interest for the first year + Interest for the second year + Interest for third year = Rs. (400 + 420 + 441) = Rs.1261

Find the area of the figure ​

Answer»

Question :- find the area of the figure

Answer :-

         your ans is 495 cm^2

constuction :-

                draw DC ⊥ AE .

∴ ABCD is a rectangle

∴ BC = AD

∴   AD = 25

∴   BD = 30-25=5 cm

therefore ,

               Area of ABCD

                        = 18* 25 cm^2

                        = 450 cm^2

∴ AB = DC      [ as ABCD is a rectangle ]

so,

    DC = 18 cm

as,

      DCE is a Right angle Δ .

∴ Area of ΔDEC  

                = = \frac{1}{2} * DE * DC\\= \frac{1}{2} *5 *18\\= <klux>45</klux> cm^2

∴ Area of given figure is 45 + 450 = 495cm^2

our answer is 495cm^2.

thank you.

Amit drives a car daily to his office from his home. The distance is 24km. On a particular day, he left his home at 8 :15 AM, drove for 5km at a speed of 60kmph. After that he was stuck in a traffic jam of 1km during this stretch he could drive only at a speed of 15kmph.Which of these is the closest to the minimum speed at which he should drive after the traffic jam to ensure that he reaches the office by 8:45 AM? ( Assuming that he can drive the way he wants to, without any traffic jams)

Answer»

GIVEN:

Distance of office

case-1:

AMIT drove 5 km at 60 kmph

case-2:

He was struck in traffic of 1 km at a speed of 15 kmph

Solution:

We have Speed=\frac{Distance}{Time}

CASE-1:

speed=60×5/18  m/s = 50/3 m/s

distance=5000 m

so, \frac{50}{3} =\frac{5000}{time}

time=300 seconds = 5 minutes

So he travelled 5 km distance in 5 minutes i.e., by 8:20 AM

CASE-2:

speed=15×5/18 =25/6 m/s

distance = 1000m

so,  \frac{25}{6} =\frac{1000}{time}

time = 240 seconds = 4 minutes

So now by 8:24 AM he travelled a distance of 6 km

Now the distance to be travelled = (24-6)km = 18 km= 18000 m

And time left = 21 minutes = 1260 seconds

Now , Speed=\frac{18000}{1260}

         Speed = 14.28 m/s

         Speed = 14.28 × 18/5  kmph

         Speed = 51.42 kmph

Here after traffic JAM Amit has to drive with a minimum speed of 51.42 kmph

So 60kmph is CLOSEST to the minimum speed he should drive after the traffic jam.
