13.let the total number of students be 'x'
2/5× x----> car
1/4× x-----> bus
(x-13x/20) 1/3---> walk on their own
(x-13x/20) 1/3=224
x-13x/20=672
7x=13440
x=1920
there are 1920 students in that school
14.
Let the contribution of Mother be x then the elder one's will be 3/8x and the younger one's will be x/2
According to the Question:
x+3/8x+x/2 = 60000
8x+3x+4x/8 = 60000
15/8x = 60000
x = 60000 * 8/15
x = 4000 * 8
x = 32000
Mother's contribution = ₹32000
Elder one's = 3/8*32000
→ 3*4000
→ ₹12000
Younger one's = 32000/2
→ ₹18000
