Example no.31 page no. 896 R s Aggarwal plzzz sir can u tell me how i solve this ...thankyou

[@Yeah-pb4uu]

The first question was quite easy,The answer to the second question is -He went at the speed of 20kmper hour and came back with the speed of 30km/h soln time=distance/speed distance travelled 150 n let speed be x 150\x+10-150/x=5\2(time taken) take 150 common 150(1/x+10-1/x)=5/2 after solving this u will get -600/x^2 + 10x=1 x^2+30x-20x+600 x=20(After taking common)

[@MamtaKumari-ct3kj]
