13.	The distance of the college and the home of Rajeev is 80km. one day he was late by 1 hour than the normal time to leave for the college,so he increased his speed by 4kmph and thus he reached to college at the normal time. The increased speed of Rajeev is.
Answer» Answer: The increased speed of Rajeev = 20 km/h Step-by-step EXPLANATION: Distance between home and college = 80km Let the speed is V and time t Distance = Speed × Time 80 = vt .......... (1) When he increases the speed by 4 KMPH he still reaches the college at time while starting 1 HOUR late Hence 80 = (v+4)(t-1) ⇒ 80 = vt + 4t - v - 4 ⇒ 80 = 80 + 4t - v - 4 ⇒ 4t = v + 4 ⇒ t = (v + 4)/4 Putting this value in eq (1) 80 = v (v + 4)/4 $v^2+4v=320$ $v^2+4v-320=0$ $\implies v^2+20v-16v-320=0$ $\implies v(v+20)-16(v+20)=0$ $\implies (v+20)(v-16)=0$ $\implies v=16, -20$ v cannot be negative Thus, v = 16 km/h The increased speed of Rajeev = 16 + 4 = 20 km/h Hope the answer is helpful.

The distance of the college and the home of Rajeev is 80km. one day he was late by 1 hour than the normal time to leave for the college,so he increased his speed by 4kmph and thus he reached to college at the normal time. The increased speed of Rajeev is.

Answer»

Answer:

The increased speed of Rajeev = 20 km/h

Step-by-step EXPLANATION:

Distance between home and college = 80km

Let the speed is V and time t

Distance = Speed × Time

80 = vt .......... (1)

When he increases the speed by 4 KMPH he still reaches the college at time while starting 1 HOUR late

Hence

80 = (v+4)(t-1)

⇒ 80 = vt + 4t - v - 4

⇒ 80 = 80 + 4t - v - 4

⇒ 4t = v + 4

⇒ t = (v + 4)/4

Putting this value in eq (1)

80 = v (v + 4)/4

$v^2+4v=320$

$v^2+4v-320=0$

$\implies v^2+20v-16v-320=0$

$\implies v(v+20)-16(v+20)=0$

$\implies (v+20)(v-16)=0$

$\implies v=16, -20$

v cannot be negative

Thus, v = 16 km/h

The increased speed of Rajeev = 16 + 4 = 20 km/h

Hope the answer is helpful.

10 masons can build a wall, working 6 hours a day, in 16 day. In how many days can the work be completed by 12 masons working 8 hours a day?

Answer»

Answer: 10 DAYS

Step-by-step explanation:

work by 10 masons in 1 day = 1/16

work by 10 masons in 1 HOUR= 1/16 /6 = 1/96

work by 1 mason in 1 hour =1/96 /10 = 1/960

work by 12 mason in 1 hour =1/960 * 12 = 1/80

work by 12 mason in 8 HOURS = 1/80*8 = 1/10

day required =x

x/10 = 1

50.	two circular cylinder of equal volume have their height in the ratio 1:2 find the ratio of their radius
Answer» ANSWER: VOLUME of CYLINDER V= πr^2h r^2 = V/πh volume of cylinders: V1&V2 height=h1&h2 radius=r1&r2 ri^2 = V1/πh 1 r2^2 = V2/πh 2 r1^2/r2^2 =VI/πhi/V2/πh 2 here hi:h 2 = 1:2 and Vi: V2 = I: I r12/r2^2 = I/πx1/1/πx2 = 2/1 r1/r2=v2/1=v2: I.

50.

two circular cylinder of equal volume have their height in the ratio 1:2 find the ratio of their radius

Answer»

ANSWER:

VOLUME of CYLINDER V= πr^2h

r^2 = V/πh

volume of cylinders: V1&V2

height=h1&h2

radius=r1&r2

ri^2 = V1/πh 1

r2^2 = V2/πh 2

r1^2/r2^2 =VI/πhi/V2/πh 2

here hi:h 2 = 1:2 and Vi: V2 = I: I

r12/r2^2 = I/πx1/1/πx2 = 2/1

r1/r2=v2/1=v2: I.
