A housewife saved Rs.2.50 in buying an item on sale. If she spent Rs. 25 for the item, approximately how much percent she saved in the transaction?
Actual price = Rs.25 + Rs.2.50 = Rs.27.5
Saving = Rs.2.5
= 2.5/27.5 × 100 = 250/27.5 = 2500/275
= 100/11 = 9 1/11%

Two trains having length of 140 meter and 160 meter long run at the speed of 60 km/hr and 40 km/hr respectively in opposite directions (on parallel tracks). The time which they take to cross each other, is
Distance =(140+160)=300 m=0.3 km
Relative speed = (60+40) =100 km/hr
Required time = 0.3/100 hr
= 0.3/100 × 3600 seconds
= 10.8 seconds
