Answer:
1)How old is a man whose age fifteen years ago was two-fifths of
what it will be in 6 years?
Let say Man is M years
15 years ago = M - 15
after 6 Year = M + 6
2/5 of after 6 years = (2/5)(M + 6)
=> M - 15 = (2/5)(M + 6)
=> 5M - 75 = 2M + 12
=> 3M = 87
=> M = 29
Man is 29 Years old
2)
Distance covered by Rehana going hospital = 12.5 km
Charges for 1st 5 km = 32.75 Rs
charges for remaining = (12.5- 5) * 9.5 = 71.25 Rs
Amount = 32.75 + 71.25 = Rs 104
Distance covered by Rehana while returning= 12.5 + 2.3 = 14.8 km
Charges for 1st 5 km = 32.75 Rs
charges for remaining = (14.8- 5) * 9.5 = 93.1 Rs
Amount = 32.75 + 93.1 = Rs 125.85
Total amount to be paid = 104 + 125.85 = 229.85 Rs
3)
Let say cost of Eraser = E Rs
Cost of Pencil = 2E Rs
8 * 2E + 4E = 100
=> 20E = 100
=> E = 5
Cost of Eraser = rs 5
Cost of Pencil = Rs 10
