a school has 200 students. one third of the boys have blue eyes and one quarter of the girls have blue eyes. given that a total of 57 students have blue eyes how many boys attend the school |
|
Answer» let number of boys attend the school be X HENCE number of girls attend the school =200-X Number of boys with blue EYES = 1/3×X = X/3 Number of girls with blue eyes = 1/4×(200-X) = 200-X/4 ATC (X/3) + (200-X/4) = 57 (4X+600-3X/12) = 57 (X+600/12) = 57 (X+600) = 57×12 X = 684 - 600 X = 84
hence number of boys attend the school = X = 84 |

Answer» Let the 2 consecutive odd integers be n and n+2.
n(n + 2) = 99
Solve for n.
n2 + 2n - 99 = 0
(n + 11)(n - 9) = 0 ⇒
TWO solutions:
n = -11 n + 2 = -9
and
n = 9 n + 2 = 11
Test the answers. ORLet the two consecutive odd integers be x and x +2 x +2 Given :- x(x+2) = 99 x² + 2x = 99 x² + 2x - 99 = 0 splitting the middle TERM :- x² + 11x - 9x - 99 = 0 x( x + 11) - 9(x + 11) =0 (x - 9) ( x + 11) = 0 x = 9 , x = - 11 x = 9 is the value taken here :- x = 9 x + 2 = 9 + 2 = 11 The no:s would be 9 and 11 Hope this HELPS.... ✌✌☮☮✌✌ |
