* 问题详情,请 查看题干

问题如下:

5. Fromm’s sensitivity analysis will result in a decrease in the 2015 base case gross profit margin closest to:

选项:

A.

0.55 percentage points.

B.

0.80 percentage points.

C.

3.32 percentage points.

解释:

A is correct.

The sensitivity analysis consists of an increase of 20% in the price of an input that constitutes 4% of cost of sales. Change in grossprofit margin because of that increase is calculated as the change in cost of sales because of price increase divided by sales:

= (Cost of sales × 0.04 × 0.2)/Sales

= (105.38 × 0.04 × 0.2)/152.38

= 0.0055

老师好,请问一下以下这种思路哪不对呢,分别求出metal涨价前的Gross profit margin和涨价后的gross profit margin. 然后选C

嗨,努力学习的PZer你好:


你的计算思路没有问题,答案不一样是因为你的计算里面有个小错误,括号里COGS增长的部分乘的不是1.2,而是0.2。 因为你后面已经加上全部的COGS了,再乘1.2,相当于重复计算了。不知道我这样说你能否理解。

NO.PZ201512300100000705 老师好 为什么 这里分母不是乘以 1.2 而是乘以0.2 “(Cost of sales × 0.04 × 0.2)/Sales” 谢谢 , 讲义里 有总结过 increase xx from xx , 是 + x%; increase x%是指 G *(1+x%)。 题中”increase “ 该怎么理解 是和incease X% 的意思不同的,是吗?
