Direction: What value should come in place of question mark (?) in the following question? |
A) 2995
B) 2623
C) 3000
D) 2351
E) 2105
Correct Answer: C
Solution :
60% of 6200 - 105% of ? = 570 Or, \[\frac{60}{100}\times 6200-\frac{105}{100}\times ?570\] Or, \[?=(60\times 62-570)\times \frac{100}{105}\] \[=(3720-570)\times \frac{20}{21}=\frac{3150\times 20}{21}\] \[\therefore ?=\frac{63000}{21}=3000\]You need to login to perform this action.
