In a certain code language, "JAM" is written as "72" and "RIPE" is written as "144". How is "BEAR" written in that code language?
Sum of the position of letters is given multiplied by 3 JAM = 10 + 1 + 13 = 24 x 3 = 72 RIPE = 18 + 9 + 16 + 5 = 48 x 3 = 144 BEAR = 2 + 5 + 1 + 18 = 26 x 3 = 78
How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
I. x= √(20+ √(20+ √(20+ √(20…………….∞)) ) )
II. y= √(5√(5√(5√(5……….∞)) ) )
...I. 5x + y = 37
II. 4y+ x = 15
I. 8x² - 78x + 169 = 0
II. 20y² - 117y + 169 = 0
I. 20x² - 93x + 108 = 0
II.72y² - 47y - 144 = 0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 2y2 - 15y + 18 = 0
II. 2x2 + 9x - 18 = 0
I. 2x2 – 10x – 48 = 0
II. y2 – 16y – 297 = 0
I.√(3x-17)+ x=15
II. y+ 135/y=24
I. 20y² - 13y + 2 = 0
II. 6x² - 25x + 14 = 0
