Answer the questions after reading the information provided hereunder:
Amarjothi Company, Bimaljalan company and Cindria Company produce computers in two different types X and Y. Total number of items of both types produced by all the three companies is 62000 and total items X and Y produced by amarjothi company is 15200. The ratio of the numbers of type X to type Y produced by amarjothi company is 9:10. Type X produced by Bimaljalan company is 175% of type X item produced by amarjothi company. Total items (both X and Y) produced by Bimaljalan company is 150% of total items produced by amarjothi company. The number of type X item produced by Cindria company is 20% more than the number of type Y items produced by Amarjothi company.
What is the number of Y type items produced by Bimaljalan company?
Answer: a) 10200
it is given amarjothi company produces 15200 and items X and Y in the ratio 9:10.
Type X items produced by amarjothi company -15200 x 9/19=7200
Type Y item=15200-7200=8000
Bimaljalan company’s total production – both X item and Y item-is 150% of the items produced by amarjothi Company—15200*1.5=22800(150% means multiply the given number by 1.5)
Type X produced by Bimaljalan company is 175% of type x item produced by Amarjothi Company.
Y type item produced by Bimaljalan company=22800-12600=10200
Calculate the ratio of the number of type X item to type Y item produced by Cindria company?
Answer: d) 2:3
Number of items produced by amarjothi company-15200
Number of items produced by Bimaljalan company-22800
Number of items produced by Cnidria company-24000.
The number of type X item produced by cindria company is 20% more than the number of type Y items produced by Amarjothi company.
Number ,Y type items produced by amarjothi company-8000
X type produced by cindria company -8000*1.2=9600.
Y type produced by cindria company=24000-9600=14400
