The mean proportional b/w two numbers is 9 and the third proportional of the two numbers is 243. Find the larger of the two numbers.

Reply Like? Yes (1) | No (3)

(9 years ago)

Hi your answer is 27
Let me explain this is how
a,b are numbers
Sqrt(a.b)=9

=> a.b=81
=> a =81/b------>(1)
also.
a,b,243 are in proportion
=> a/b = b/243
=>a(243)=b^2
=>(81/b)(243)=b^2. Using (1)
=>(3^4/b)(3^5)=b^2
=>3^9 =b^3
=>3^3 =b
=>27=b
From ab=81
=>a(27)=81. From b=27
=>a=3
Therefore the numbers are 3,27
Greatest number=27

Like? Yes (7) | No (1)

(9 years ago)

let the numbers be a and b .
then acc to mean proportion relation is a:9::9:b
and acc to third proportion relation is a:b::b:243
from above we get two equations ab=81
and b^2=a*243
Solving these two we get
a=3
b=27
So larger is 27.

If original price/Kg. of sugar=x then in Rs. 500, quantity can be purchased=500/x
With increase in 25% of price, new quantity purchased=500/[(125/100)*x]
As difference in quantity purchased=5 Kg, So 500/x - 500/[(125/100)*x]=5
