father shared an amount of rs. 33,201 to his two sons and their shares are invested at a compound interest of 4% per annum. if the amount received by the elder son at the end of 2 years is the same as the amount received by the younger son at the end of 5 years, then the share (in rupees) of the younger son is

Hi Ajay Kumar, Let the share of elder son be x and younger son be y. x + y = 33201 It is given, x(1+4/100)^2 = y(1+4/100)^5 x = y(1+4/100)^3 33201 - y = y(26/25)^3 33201 = y(33201/15625) y = 15625 Hope this helps!

I score 84% in 10th, 68% in 12th and have 9 cgpa in UG. I'll be graduating this year so, no work EX. Non-Engineering, female. What all IIms do i have a shot at? Is IIM calcutta possible?

IIM Calcutta is nearly not possible since with 68% in 12th, even with other parameters considered, you would need 99.98+. I didn't get a call at 99.61%ile with 10th/12th 94/86.8 (GEM). IIM C doesn't take grad/workex/acad-diversity during call. Female usually get call at 98.6%ile+ if both 10th/12th are 80+.

Hi, if you belong to the General category, the required percentile would be a bit high for IIMC. However, you have good chances to get calls from other top IIMs. You can check the required percentile based on your profile here: https://cracku.in/cat-percentile-required-for-iim-calls

The average weight of boys in a class is 40 and girls is 60. The average weight of the entire class is 45. 8 new boys joined and their average weight is 80. After the addition of these new boys, the average weight increased by 7. What is the initial number of boys and girls in the class respectively? Can this question be solved using Aligations?

40 60 45 15 : 5 3K : 1K 80*8+120K+60K/ 4k+8 = 52 K= 8 Boys : 24 and Girls : 8

Hi Meghana, Let the initial number of boys and girls be x and y respectively. It is given, 40x+60y/x+y = 45 5x = 15y x = 3y It is also given that, 40(3y) + 640 + 60y/4y + 8 = 52 Solving, we get y = 8 and x = 24 Therefore, the number of boys and girls initially is 24 and 8, respectively. Hope this helps!
