Answers
Answer:
86,250 students failed in both science and math
Given,
Out of 1,15,000 students 20% failed in exam
40% of the failures failed in science only
35% in mathematics only
But 5% of them. failed in other subject
I) how many failed in both science and math?
= 40% × 1,15,000 + 35% × 1,15,000
= 40/100 × 1,15,000 + 35/100 × 1,15,000
= 4 × 11500 + 35 × 1150
= 46000 + 40250
= 86,250
Therefore, a total of 86,250 students failed in both science and math
II) show the information in venn diagram
1,15,000
40% × 1,15,000 = 46,000
35% × 1,15,000 = 40,250
5% × 1,15,000 = 5,750
20% × 1,15,000 = 23,000
Step-by-step explanation:
Answer:
86,250 students failed in both science and math
Given,
Out of 1,15,000 students 20% failed in exam
40% of the failures failed in science only
35% in mathematics only
But 5% of them. failed in other subject
I) how many failed in both science and math?
= 40% × 1,15,000 + 35% × 1,15,000
= 40/100 × 1,15,000 + 35/100 × 1,15,000
= 4 × 11500 + 35 × 1150
= 46000 + 40250
= 86,250
Therefore, a total of 86,250 students failed in both science and math
II) show the information in venn diagram
1,15,000
40% × 1,15,000 = 46,000
35% × 1,15,000 = 40,250
5% × 1,15,000 = 5,750
20% × 1,15,000 = 23,000
