41. The H .C .F of 1600 and 125 is 25.
Length wise---- I can cut 64 breadthwise. 5 pieces
Altogether I can cut 320 pieces.
42. Let the numbers be H pH q Where H is their H. C. F. and p
q are prime to each other.
Then, their L.C. M = Hpq
Hp + Hq = 85 H pq = 102
Dividing , p + q / pq = 85 / 102 = 5 /6
Therefore the numbers p,q must be 3 2
H = 102 / 6 = 17
Therefore A = 17 * 3 = 51 B = 17 * 2 =34
43. Triangle SAB is similar to triangle SFL
SA / SF = AB / FL
x /x + 4 = 1.75 / 5.25 = 1/ 3

21 + r 2= 23
Therefore r 3= 8
R 1 = 13

If the original area is 'A'
then new area = 4 A
increase in area = 4 A - A = 3A
Therefore % increase = 3 A / A * 100
