Let Arif's share be x. Hafiz's share is 4x, and Arif's share is one-third of Haider's, so Haider's share is 3x. Total shares: x + 4x + 3x = 8x = 2560, so x = 2560/8 = 320. Therefore, Arif's share is Rs. 320.

The word 'blatant' means something very obvious or conspicuous, often in an offensive or shameless way. Among the options, 'Obvious' is the correct synonym.

The total age of A, B, C, D, and E is 40 × 5 = 200 years. The total age of A and B is 35 × 2 = 70 years, and the total age of C and D is 42 × 2 = 84 years. Therefore, the age of E = 200 - (70 + 84) = 46 years. However, since 46 is option B, the correct answer is B.

The United States is widely recognized as the world's top supplier of weapons, leading global arms exports by a significant margin compared to other countries such as Russia, Israel, and Germany.

A and B together complete the work in 15 days, so their combined rate is 1/15 work per day. B alone completes the work in 20 days, so B's rate is 1/20 work per day. Therefore, A's rate is (1/15 - 1/20) = (4/60 - 3/60) = 1/60 work per day, meaning A alone can complete the work in 60 days. However, since 60 is option A, the correct answer should be A, not D. Rechecking the calculation: A's rate = 1/15 - 1/20 = (4 - 3)/60 = 1/60, so A alone takes 60 days. So the correct answer is A.

The term 'largest airport' can refer to different metrics such as land area, passenger traffic, or terminal size. The largest airport in the world by land area is King Fahd International Airport in Dammam, Saudi Arabia, covering about 776 square kilometers. Dubai International Airport is one of the busiest airports by international passenger traffic and has the world's largest terminal by floor space, but it is not the largest airport overall by land area or total passenger traffic. The busiest airport by total passenger traffic in 2024 is Hartsfield-Jackson Atlanta International Airport in the USA. Therefore, none of the given options (New York airport, Frankfurt airport, Dubai Airport) is the largest airport in the world by the broadest definition. Hence, the correct answer is 'D' (None of these).

The word 'valiant' means showing courage or determination. The opposite is 'cowardly', which means lacking courage. Therefore, option B is the correct antonym.

Mount Everest, the world's highest mountain, is located in Nepal (on the border between Nepal and China). Therefore, the correct answer is Nepal.
