Formula:- (SI=PRT/100) >SI-390 >P-1800 >R-5/365 390=1800*5*T/100*360(>>leave 5 days and add with the final result, its helps in easy calculation). T=1560(and add 5 days with this result) T=1560+5=1565. T=1565 days, x=4years=1460 days, T-x=1565-1460=105 da...

Speed of car = 50 km/hr Time taken = 30 min = 30/60 hr = 0.5hr Distance to airport => Speed = Distance / time 50 = distance to airport/ 0.5 Distance 50*0.5 = 25km Required time to reach airport is 25 min = 25/60 hr Distance = 25 km Required speed = distan...

The parallelogram has sides 15cm 20cm 15cm 20cm The diagonal of length 25cm divide it into two congruent triangles Using the heron formula to find the area of a triangle and multiplying by two we get the area of parallelgram Triangle with sides 15cm 20 cm...

Both are correct
