Question:

In a race of 1 km, A gives B starting lead of 40 m and to C starting lead of 70 m. Find starting lead that B can give to C in same race?

Options:

30 m

31\(\frac{3}{4}\) m

31\(\frac{1}{4}\) m

32 m

Correct Answer:

31\(\frac{1}{4}\) m

Explanation:

Distance covered :-

                               A       :            B             :          C

                            1000    :      (1000-40)     :     (1000-70)

                            1000    :         960            :        930

                                                    ⇓                        ⇓   

                                                             diff. = 30

Hence,

In 960 meter race →B gives 30 meter start to C, and

In 1000 meter race B gives → \(\frac{30}{960}\) × 1000 = 31\(\frac{1}{4}\) meter start to C.
