We know, the probability of an event = Favorable outcomes / Total outcomes. In a case of two dices, Total outcomes = 6 × 6 = 36 A.T.Q favorable outcome is a sum of 6, Ways of obtaining a sum of 6 (1,5), (5,1), (2,4), (4,2) and (3,3). Thus, there are 5 ways in which 6 can be obtained using two dices. Therefore, required probability, P = 5/36
Let the Market Price of the product is MP. Let the Original Cost Price of the product is CP. Selling Price (Discounted Price) = 100% of MP - 20% of MP = 80% of MP ......... (1) Profit made by selling at discounted price = 20% of CP ........... (2) Apply the formula: Profit = Selling Price - Original Cost Price ⇒ 20% of CP = 80% of MP - 100% CP ⇒ MP = (120×CP)/80 = 3/2 × CP Now if product is sold without any discount, then, Profit = Selling Price (without discount) - Original Cost Price = Market Price - Original Cost Price = MP - CP = 3/2 CP - CP = 1/2 CP = 50% of CP
∴ 12 জন পুরুষ 1 দিনে করে 1/24 অংশ আবার, 12 জন মহিলা 12 দিনে করে 1 অংশ ∴ 12 জন মহিলা 1 দিনে করে 1/12 অংশ তাহলে, 12 জন পুরুষ ও 12 জন মহিলা 1 দিনে করে = (1/24 + 1/12) অংশ = (1+2)/24 অংশ = 3/24 = 1/8অংশ
নারী এবং পুরুষেরা একত্রে 1/8 অংশ করে 1 দিনে ∴ তারা একত্রে 1 বা সম্পূর্ণ অংশ করে 1×8 = 8 দিনে

আরো উদাহরণঃ - If motorists do not observe the traffic regulations, they will bestopped, ticketed and fined. - The kid likeswatchingcartoons andeatingchocolates.

সঠিক উত্তর
1 (She was disguised lest she should be recognized.)
ব্যাখ্যা:
lest এর পরের Clause এ Should/ might বসে। lest নিজেই Negative হওয়ায় এর পর আর কোনো negative শব্দ no/not/never বসে না। - Work hard lest you should fail. - He walked fast lest he should miss the train. - She was disguised lest she should be recognized.
প্রশ্নোল্লিখিত বাক্যে কর্তার উল্লেখ না থাকায় বাক্যটি passive হবে এবং যেহেতু বাক্যটি অতীতে কোনো চলমান ঘটনার বর্ণনা দিচ্ছে তাই এটির passive form continuous হবে।
