Let us assume the first part is A then second part will be 50 - A.
According to question,
Sum of their reciprocals is 1/2.
1/A + 1/(50 - A) = 1/12
? (50 - A + A)/(50 - A)A = 1/12
? (50)/(50 - A)A = 1/12
? (50) x 12 = 1 x (50 - A)A
? 600 = (50 - A)A
? 600 = 50A - A2
? A2 - 50A + 600 = 0
? A2 - 30A - 20A + 600 = 0
? A(A - 30) - 20(A - 30) = 0
? (A - 30)(A - 20) = 0
? (A - 30) = 0 or (A - 20) = 0
? A = 20 , 30
The value of | (0.96)3 - (0.1)3 | is: |
(0.96)2 + 0.096 + (0.1)2 |

Total share given by a person
= (1/4) + (1/2) + (1/5)
= (5 + 10 + 4)/20
= 19/20
Since a * b = a + b + a/b
? 12 * 4 = 12 + 4 + 12/4
= 12 + 4 + 3 = 19
According to the formula,
Required time = ?ab
Where a = 25 and b = 49
? Require time = ?25 x 49 = 5 x 7
= 35 days
Due to the rise in the rate of interest, annual income increases by Rs . (8 - 61/ 2) = Rs , 11/ 2
, when the capital is Rs . 100
Thus, the required capital = (100 x 2 x 4050) / 3 = Rs. 270000
So, the next number is (2 x 261 + 1) = 523.
Let 16.7 + 12.38 - x =10.09
? x = 16.7 + 12.38 - 10.09
= 18.99
