Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:One-fourth of sixty percent of a number equals two-fifths of twenty percent of another number, and the ratio is 8 to 15.
Statement II:The student studies 9 hours on each of 5 weekdays and 3 hours on Saturday; the fraction of the whole week studied is 3/7.
ABoth Statement I and Statement II are true
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false ✓ Correct
DStatement I is false but Statement II is true
Correct answer: (C) Statement I is true but Statement II is false
Explanation
Statement 1 is true but Statement 2 is false.
(1/4)(0.6x) = (2/5)(0.2y) gives 0.15x = 0.08y.
so x : y = 8 : 15, matching Statement 1.
study hours = 5 x 9 + 3 = 48 in the week.
total week = 7 x 24 = 168, fraction = 48/168 = 2/7.
this is not 3/7, so Statement 2 fails.
