Question 3. If A Man Travels With 5/6th Of His Usual Speed, He Is Late By 15 Mins. What Is The Usual Time Taken To Travel ?

Answer :

Suppose man's regular pace = s, and normal time = t

So distance = speed *time ==> d= s*t

If he travels with five/sixth of his regular pace that is = s*five/6

And time= (t+15) and distance, d = (s*5/6)*(t+15) as distance could be same

s*t = (s*5/6)*(t+15)

t= (5t+seventy five)/6

t= 75 min.

Answer :

(483*483*483+ 517*517*517) / (517*517 - 517*483 + 483*483) a3+b3

= (a+b)(a2-ab+b2) Hence [(a+b)(a2-ab+b2)] / (a2-ab+b2)

= a+b In the given equation a=483 and b= 517

==> 483+517=1000.

During A Period Of Five Hours, R Can Type As Many Pages As P Can During Seven Hours. How Many Pages Does Each Of Them Type Per Hour ?

Answer :

Let's the variety of pages typed in a single hour by P, Q and R be p, q and r respectively. Then,

P,Q and R typed web page in 1 hrs = 216/4

=> p + q + r = 216/4

=> p + q + r = 54 ...(i)

r - q = q - p => 2p = q + r ...(ii)

5r = 7p => p = five/7 r ...(iii)

By Solving above (i), (ii) and (iii) equations

=> p = 15, q = 18, q = 21

A = (40500 * 6 + 45000 * 6) = Rs. Five,13,000

B = (45000 * 12) = Rs. Five,forty,000

C = (60000 * 6 + 45000 * 6) = Rs. 6,30,000

Ratio A : B : C = 513 : 540 : 630

C's percentage will exceed that of A via

= [(630 - 513)/1683] * 56100 => (117/1683) * 56100
