total mangoes(good + rotten ) = 100%
25% rotten means 25% = 1250
then 100% = (1250/25)×100 = 5000
total mangoes = 5000
if 25% rotten then 75% will be good
so 75% = 5000-1250 = 3750
25% rotten means 25% = 1250
then 100% = (1250/25)×100 = 5000
total mangoes = 5000
if 25% rotten then 75% will be good
so 75% = 5000-1250 = 3750

Step-by-step explanation:
(1) Distance travelled in first 5 sec= area of ABDE= 20×s=80m
(2) Distance travelled after the brakes are applied (area of BCD)=

×8×5=20m
(3) Total distance travelled= AreaofABCDE+AreaofBCD=80+20=100m
(4) Acceleration during the first 5 sec= 0, because uniform velocity.
(5) Acceleration during the last 8 sec= v=0,u=20m/s,t=8sec
⇒v=u+at⇒0=20+a(8)
⇒a=−2.5m/s
