Q:

A) 60 | B) 55 |

C) 45 | D) 40 |

Answer & Explanation
Answer: A) 60

Explanation:

Explanation:

From the given data,

let the length, breadth and height of the cuboid are m, n, r

m x n = 12

n x r = 20

r x m = 15

Hence, m x n x n x r x r x m = 12 x 20 x 15

mnr = sqrt of (12x20x15) = **60 cub.cm.**

Q:

A) 19 kmph | B) 13 kmph |

C) 7 kmph | D) 9 kmph |

Answer & Explanation
Answer: A) 19 kmph

Explanation:

Explanation:

Let the speed of the slower train = p kmph

ATQ,

Speed of the faster train = (p + 6) kmph

Then,

(p + p + 6) x 5 = 160

10p + 30 = 160

10p = 130

p = 13 kmph

Then, speed of the faster train = p + 6 = 13 + 6 = **19 kmph**.
