7th problem is not clear sir.distance covered mein 7+8+4 to samajh aya lekin 15 ko kyun add kiya?jana to b mein hai na.8 ko to add karna chahiye

Yes

F to B jana hai taking 2 turns via A

to path hoga – F T A B

so FT + TA + AB

AB = 15

vo 15 add kiya hai

ok mam got it

T kha se aaya

(7+8+4) tak to wo..A tak aayega..but finally B point jane k liye..15 add hoga..

First five ques samjh nhi aaye

7 ques samjh nhi aaya

Ye t kha se aaya ab ques main mentioned to hai nhi

T to hai nhi

Mam t kha se aaya

konsa t?

7 ques

are a ke bara bar 1 point liya hain b se a 15 km south lekin b se h ke bara bar point lo to distance 16 matlab a se h ke parallel point ka dis =1 so a tak jana hain to f se 7 km jana hoga phir right murne ke baad a milega

Dimaag hi kharab kiya hua

T suppose kiya h

1.Now for next 45 minutes, 1 red & 3 green lights, means turned right and drove at 60 km/hr, so covered 45/60 * 60 = 45 Km

yhan pe gdbdi lg rhi

…………

45/60 * 80 = 60 Km ye hona chiye

see that admin..

Doubt discussion check plz. I posted one qued

T se bhi chala to minus kyu kiya

T se chal Kar bhi 32 aa jayega ans

niche likha hain maine
