Q6. Cannot Say....... (No concrete Cost figure given)
Q16 = 20 days
According to question, GBP and Euro continues to rise by same amount ie, 0.42 and 1.68 every day
So, lets PLUG-IN 30 days....lets see what happens after 30 days
GBP= 70.72+ (0.42 x 30)= 83.32
Euro = 46.61+(1.68 x 30)= 97.01
But, Pluging 20 days results into:
GBP=70.72+(0.42 x 20) = 79.12
Euro= 46.61+(1.68 x 20) = 80.21
Q18 = 2,805,000
Trader buy 15000 GBP.
Ngultrums = GBP 15,000 x 71.06= 1,065,900
Maximum Yen a trader can buy is when Yen is at lowest i.e, 0.38
Maximum Yen brought = 1,065,900 / 0.38 =2,805,000
Q20 = 5830 million
5 years ago, 2.1 x 1000 million passengers traveled compared 3.5 x 1000 million in this year
% increase in 5 years = 66.66%
The rate remains constant for next 5 years
Total passengers traveled by air = (3.5 x 1000m)+ (3.5 x 1000m x 0.6666)= 5,833.1 million, which is very near to 5,830 million
Q 17. = 67.60
Todays ratio = 70.72/68 = 1.04
This ratio was/is constant
Yesterdays ratio = 1.04
1.04= 70.3/World Bank (70.3= Closing GBP today-Todays Increase i.e, 70.72-0.42= 70.3)
World Bank = 67.59615 which is appox near to 67.60
Pls if somebody can explain GMAT appox rules, would be appreciated. ( Is Rounding up and Down of answers allowed?)
