QUESTION: একটি bus 1 liter diesel ব্যবহার করে 15 km যায়। Engine tune-up এর পর, bus টি 1 liter-এ 15% বেশি দূরত্ব অতিক্রম করে। Tune-up এর পর 150 km যেতে bus টির কত liter diesel লাগবে (নিকটতম দশমিকে)? *প্রথমে, tune-up এর পর bus টি 1 liter diesel-এ কত km যেতে পারে তা বের করতে হবে: আগে: 15 km -15% বৃদ্ধি: 15 km এর 15% = 2.25 km -মোট: 15 + 2.25 = 17.25 km *এখন, 150 km যেতে কত liter diesel লাগবে তা হিসাব করতে হবে: -150 km / 17.25 km per liter = 8.6957 liter *উত্তরটিকে নিকটতম দশমিকে প্রকাশ করলে পাই 8.7 liter। -সুতরাং, tune-up এর পর 150 km যেতে bus টির 8.7 liter diesel লাগবে, যা option (B)-তে দেওয়া আছে।Related questions
A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is:Speed of a boat in standing water is 9 kmph and the speed of the stream is 5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:two trains are moving in opposite directions at 60 km/hr and 90 km/hr. Their lengths are 1/10 km and 9 km respectively. The time taken by slower train to cross the faster train in seconds is -A man can row three-quarters of a kilometre against the stream in 11×(1/4) minutes and down the stream in 7×(1/2) minutes. The speed (in km/hr) of the man in still water is:In a 300 m race A beats B by 5 metre or 6 seconds. B's time over the course is -A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along the current in 10 minutes. How long will it take to go 5 km in stationary water?A boat covers a certain distance downstream in 1 hour, while it comes back in 1x(1/2) hours. If the speed of the stream be 3 kmph, what is the speed of the boat in still water?A man buys tk 20 shares paying 9% dividend. The man wants to have an interest of 12% on his money.
