Q:

A) Rs. 600 | B) Rs. 768 |

C) Rs. 878 | D) Rs. 668 |

Answer & Explanation
Answer: B) Rs. 768

Explanation:

Explanation:

We know that,

P.W = 100×T.D/R×T

= 100×168/14×2

P.W = 600.

Now, required Sum = (P.W. + T.D.)

= Rs. (600 + 168)

= Rs. 768.

Q:

A) Rs.948 | B) Rs.876 |

C) Rs.768 | D) Rs.658 |

Answer & Explanation
Answer: C) Rs.768

Explanation:

Explanation:

P.W. = $\frac{100\times T.D}{R\times T}$ = $\frac{100\times 168}{14\times 2}$ = 600.

Sum = (P.W. + T.D.) = Rs. (600 + 168) = Rs. 768.
