    B) Rs. 625 from C

    C) Rs. 400 from B

    D) Rs. 800 from B

    Correct Answer: D

    Solution :

    [d] Let A took Rs. x from B and Rs. \[(1200-x)\] from C. Then, \[\frac{x\times 14\times 1}{100}+\frac{(1200-x)\times 15\times 1}{100}\]             = 172 \[\Rightarrow \]   \[14x+18000-15x=17200\] \[\Rightarrow \]   \[x=\text{Rs}.\,800\] Thus, A borrowed Rs. 800 from B.
