The ratio of the speeds of a train and a man is 6:1. The length of the train is 650 mand crosses a pole in 1 minute 5 seconds. In how much time will the man cross the240m long platform? |
|
Answer» Answer: 2.5 mins or 2 min 30s Step-by-step explanation: Ratio of velocity of train and man = 6:1 Length of train(L) = 650m Length of platform(L’) = 240m time taken by train to cross a pole (which we are CONSIDERING to be of negligible length ) = 1 min 5 SEC or 65 s In other words, the train travels its length in 65s [As, by the formula v=(L+L’/t) here L’ = 0; so v = L/t] speed of train = 650/65 = 10m/s Now man’s speed is simply 1/6 of train velocity, as indicated by the ratio, so speed of man = 10/6 = 1.6m/s So, time taken by the man to cross 240 m platform at CONSTANT speed then time is 240/1.6 m/s = 150 s = 2.5 mins or 2 min 30 s |

Ask someone borrowing from a five-six (Bumbay) money lender. How much will be charged if you want to loan 5,000 payable in one year? Determine the interest rate per period and the annual interest rate.It is good loan term? why or why not? |
|
Answer» Answer: Step-by-step EXPLANATION: Interest is the price you have pay to money lender of borrow money . If you borrow a Rs. 5000 personal loan, you may wind up paying the lender a total of almost Rs.5,000 over the next 1 years. That EXTRA Rs1,000 is interest. If a lender uses the SIMPLE interest method, it’s easy to calculate the interest on your loan. If you take out a one-year loan for Rs.5000 and the interest rate on the loan is 10 percent, the simple interest formula works as follows: 5,000 X 10 x 1 / 100 = 500 as in interest. But in REAL life money lender calculate as compound interest. If you are paying annually, and it's for one year than it will be same. if you are paying for more than one year it will changed totally. |
