A) n = 2 | B) n = 5 |

C) n = 29/5 | D) n = 1 |

Explanation:

Given are the two AP'S:

15,12,9.... in which a=15, d=-3.............(1)

-15,-13,-11..... in which a'=-15 ,d'=2.....(2)

now using the nth term's formula,we get

a+(n-1)d = a'+(n-1)d'

substituting the value obtained in eq. 1 and 2,

15+(n-1) x (-3) = -15+(n-1) x 2

=> 15 - 3n + 3 = -15 + 2n - 2

=> 12 - 3n = -17 + 2n

=> 12+17 = 2n+3n

=> 29=5n

=> n= 29/5

A) 3.25% loss | B) 13.742% loss |

C) 3.25% gain | D) 13.742% gain |

Explanation:

Let CP = 100,

42 % increase => SP = 142

10 % discount in SP => ((142 x 10)/100) = 14.2

So 1st SP = (142 - 14.2) = 127.8, again 12 % discount in 1st SP ((127.8 x 11)/100) = 14.058

2nd SP = (127.8 - 14.058) = 113.742,

So finally CP = 100, SP = 113.742, => gain = 13.742%.
