%Apersoninvestasandbuyscetanhumpesrl.Hewlout/ shares worth. 2400 when they have risen to 95 and the remainder when they havefallen to 285. Find the gain or loss jon the total transaction. |
|
Answer» Sum Invested by the Man = Rs. 4368Nominal Value of 1 Share = Rs. 100Market Value of 1 Share = Rs. 91 ∵ No. of Shares = Investment/M.V. of 1 Share. = 4368/91 = 48 shares. ∴ The Original Number of Shares which the Man have is 48. Now,In First Case,New Market Value of 1 Share = Rs. 95.When Market Price is Rs., 95 Man Sold 24 Shares. Sum Invested by the Man to sell 24 Shares = 24× New M.V. of 1 Share.= 24× 95= Rs. 2280. In Second Case, Number of Shares left = 48 - 24= 24 Shares.Man sold these Shares when there price fall to Rs. 85 Per Shares.∴ Market Price of One share = Rs. 85. ∴ Investment = Number of Shares× Market Value of 1 Shares. = 24× 85 = Rs. 2040 Total money gained by the main in selling these Shares = 2,280 + 2,040= Rs. 4,320Now, We can see that Money gained by the Man in selling the Shares is less than the Money Invested by the Man in buying the Shares.∴ There is a loss. Loss = Total Investment in Buying the Shares - Total Money Gained by the Man in selling the Shares.= 4368 - 4320= Rs. 48. ∴ Loss suffered by the Man during the Whole Transactions is Rs. 48. |

5.กา1) tori ned three times. Find the probability to get head or tial alternatelyFind the probability that a common year (not a leap year) contains only 52 sunday |
|
Answer» Sol: A non-leap year has 365 days A year has 52 weeks. Hence there will be 52 Sundays for sure. 52 weeks = 52 x 7 = 364 days . 365– 364 = 1day extra. In a non-leap year there will be 52 Sundays and 1day will be left. This 1 day can beSunday, Monday,Tuesday, Wednesday, Thursday,friday, saturday, Sunday. Of these total 7 outcomes, the favourable outcomes are 1. Hence the probability of getting 53 sundays = 1 / 7. 2)∴ probability of getting 52 sundays = 1 - 1/ 7 = 6 / 7. sir question solve ho gaya |
