5+3+2 = 151022
9+2+4 = 183652
8+6+3 = 482466
5+4+5 = 202541
THEN; 7+2+5 =?
Multiply the first two digits, Multiply the first and last digit, Add the previous two and subtract it from the middle number..
7 * 2 = 14
7 * 5 = 35
(14+35-2) =47
so the ans is 143547

When a cone cut by a plane at a height of h/5. then what is the ratio of volume cone and frustum ???

Reply Like? Yes | No

RAKESH 9 years ago

u hv not mentioned h/5 is upper or lower height ? vol of original cone or resulting cone

use, r/R = h/H here h can be h/5 or 4h/5 then R = 5r or R = 5r/4
use ,vol of cone = 1/3 *pi*r^2h & vol of frustum = pi*h/3 *(r^2+R^2+rR) then find ratio

For example, u have 4 red pens, 4 blue pens and 2 mixed (red+blue) pens.
So, total pens =10
actually u have 6 blue pens and 6 red pens (including mixed pens)=12 pens.
So, mixed pens=12-10=2mixed pens.

In a triangle ABC, points P1, Q1, R1 divide the lines AB, BC and AC respectively in the ratio 3 : 2 each. In the triangle P1 Q1 R1, the points P2, Q2 and R2 divide the sides P1Q1, Q1R1 and P1R1 in the ratio 3 : 2 each. A new triangle is constructed by joining the points on the sides of triangle P2Q2R2 that divide these sides in the ratio 3 : 2. This process of forming triangles continues infinitely. Find the ratio of the area of triangle P1Q1R1 to the sum of the areas of all the formed/constructed triangles (P2Q2R2, P3Q3R3…) whose areas are smaller than the area of the triangle P1Q1R1.

30L + 3Q = 1167
30L + 6Q = 1284
solving above two equations we get
3Q = 117 , Q=39 so L=35
thus cost of first 10 kg apples is 350.

Reply Like? Yes | No

Let B can finish it off in x days
B can do 1/x work in 1 days
As A is twice efficient then, A can do 2/x work in 1 days
so total work (A+B) in 1 days = 1/x + 2/x =3/x
so total time to finish the work when they work together = x/3 = 7
=> x =21 days
A can finish the work = 1/(2/x) = x/2 =10.5 days

Reply Like? Yes | No

Devendra Marghade 9 years ago

720

Here 6-digit even number is required with last two digit to be even, which is possible with last two digits as 24, 26, 42, 46, 62, 64
For last digits to be 24, first four digits can be among 1,3,5,6,7, so total 4 digits combinations from 5 digits=5P4=120
Similar 120 combinations for remaining last two digits 26, 42, 46, 62, 64 are possible.
So total 6 digit even numbers without repetition having last two digits even=120*6=720

Let the large pump fill the tank in x hours
and each of the three small pumps fill the tank in 2x/3 hours. then,
large pump 1 hour work = 1/x
each of small pump 1 hour pump = 3/2x
All fours 1 hour work = 1/x + 9/2x = 11/2x
so they can do the complete work in 2x/11 hours
so required fraction = 2x/11/x = 2/11
so answer = 2/11
