Answer : 3. "Rs. 10664.15"
Explanation :
Answer: C) Rs. 10664.15 Explanation: Profit received by Chinna as working partner = 14.5% of Rs. 19600 = 14.5x19600/100 = Rs. 2842 Balance in profit = 19600-2842 = Rs. 16758 Ratio of investment of Chinna & Munna = 80,000 : 1,40,000 = 4 : 7 Hence share of Chinna in investment = 4x16758/100 = Rs. 6093.85 Therefore, Share of Munna = 19600 - 2842 - 6093.85 = Rs. 10664.15

Answer : 3. "2"
Explanation :
Answer: C) 2 Explanation: Here the most stable carbocation is the option (2). Carbocations are always hungry for electrons. The stability of carbocations increases from primary to secondary to tertiary. Here, option (c) shows the most stable carbocation because it can easily withdraw electrons from two other carbon atoms and the more electronegative oxygen atom. Carbocation stability depends on hyperconjugation. The tertiary carbocation is stabilized by electron releasing inductive effect.

Answer :
Explanation :
You have to actually count all the balls in the pyramid.Simple way is to count the balls in each level. So lower most level lets say 1st level has 4 x 4 balls; i.e. 16 ballsSimilarly 2nd level has 3 x 3 balls; i.e. 9 balls.3rd level has 2 x 2 balls; i.e. 4 balls.The top most level has just 1 ball. So the total number of balls is 16+9+4+1 = 30. So the image has 30 Balls in all.
