Now, The equation translates to,
0.04a + .12b = .05(a+b)
but a+b= 60
therefore .04a + .12b = .05(60)
=> 4a + 12b = 300
but b=60-a
therefore
4a+ 12(60-a) = 300

If 3y + 7 = x^2 + P = 7x + 5, what is the value of P ? | [
"None of these",
"8(1/2)",
"8(1/5)",
"8(1/4)"
] | D | Explanation:
3x + 7 = 7x + 5 => 7x - 3x = 2 => 4x = 2 => x = 1/2.
Now, 3x + 7 = x^2 + p => 3/2 + 7 = 1/4 + p => p = 8 * 1/4.

Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age? | [
"4 times",
"2 1/2 times",
"2 times",

(4x + 8) = 5/2(x + 8)
8x + 16 = 5x + 40
3x = 24
x = 8.
Hence, required ratio = (4x + 16)/(x + 16) = 48/24 = 2.
