Given, A1 = ? 1350, A2 =? 1620
T1 = 5 yr and T2 = 8 yr
Let principal amount be ? P.
? In time = 8 - 5 = 3 yr
Simple interest will be
1620 - 1350 = ? 270
? R = [(A2 - A1 ) x 100] / [A1 T2 - A2 T1]
= [(1620 - 1350) x 100] / [(1350 x 8) - (1620 X 5)]
= (270 x 100)/[10800 - 8100]
= 27000/2700
? R = 10%
? P = (SI x 100) / (R x T)
= (270 x 100) / (10 x 3)
= ? 900
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
Subtract 20, 25, 30, 35, 40, 45 from successive numbers. So 0 is wrong.
NA
Each previous number is multiplied by 2.
? 8 m shadow means original height = 12 m
? 1 m shadow means original height = 12/8 m
? 100 m shadow means original height = (12/8) x 100 m
= (6/4) x 100 = 6 x 25 = 150 m
Let 8% of 96 = y of 1/25
? (8 x 96)/100 = y/25
? y = (8 x 96 x 25)/100 = 192
Since the principal is not given, so data is inadequate.
