Question
The total of ages of Nitin and Sumit at present is 60
years. Four years ago, the ratio of their ages was 6:7. Find the present age of Sumit.Solution
ATQ,
Let the present age of Nitin = y years
Then, present age of Sumit = (60 - y) years
According to the question,
(y - 4):(60 - y - 4) = 6:7
⇒ 7(y - 4) = 6(56 - y)
⇒ 7y - 28 = 336 - 6y
⇒ 13y = 364
⇒ y = 364 ÷ 13 = 28
So, present age of Sumit = 60 - 28 = 32 years
If 64x3 - 343y3 = (4x - Ay) X (Bx2 + 49y2 + Cxy), then find the value of 3 X (2A + 6B) - 2C.
If a + b + c = 8, a² + b² + c² = 18 and ab + b c+ ca = 12, then what is the value of a³ + b³ +c³ –3abc?
If
= 4 then 
(a + 7)2 + (b – 2) 2 + (c + 3) 2 = 0, then find the value of 3a - 2b + c.
Two positive numbers differ by 2, and the sum of their reciprocals is 3/4. What is the larger number?
(x + 1)2 + (y – 3) 2 + (z + 5) 2 = 0, then find the value of 2x + 3y - z.
If x + 1/x = 5, then x2 + 1/x2 is:
(x – 6) 2 + (y + 2) 2 + (z – 4) 2 = 0, then find the value of 4x - 3y + z.
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
