@bodhi_vriksha said:In a right circular cone of radius 4cm and height 10cm, largest cube is inscribed whose base rests at base of the cone. A sphere is then inserted between top of cube and the vertex of cone. What can be the maximum radius of the sphere?Team BV--Pratik Gauri
@amresh_maverick said:approx 2.06 by any chance
@pratskool said:aprox. near 1.5 cm?? options would be helpful to eliminate and use..

@techgeek2050 said:what i mean to say is thisif one of a,b,c>=10let a = a' + 10 , the equation becomesa' + b + c + k = 6similarly for b and c, a + b' + c + k = 6 , and a + b + c' + k = 6for each solution = 9C3so total = 3*9C3 ways are there wherein one of a,b,c is >=10 , so that is what should be subracted. P.S - bhai don't call me sir.. m just a noob.

@amresh_maverick said:similar to @pratskool sir,the side of the cube will be 40/9 cm . Found R which is in radius
@pratskool said:the side of the cube came out to be 40/9 cm which is the diameter of the cone in which sphere in inscribed, next sphere is like an inscribed circle in the triangle of the cone.... found the inradius of the triangle...
please solve it Question 18

@pratskool said:sirjee , itna visualisation mujhse nei hota,,, maine toh triangle main square ghusa ke kar diya...
@scrabbler said:Wohi to...instead of quad with sides x and x it will be a quad with sides x and xrt2 (the horizontal one). Bahut painful number aata hai...regardsscrabbler

@amresh_maverick said:maine to aajtak 3D mein film bhi nahi dekhiHow many integers b/w 1 and 10000 have the sum of their digits equal to 18 ?PS: @bodhi_vriksha sir ur method to solve above type of q's got over my head , bouncer
