When 60% of a number is subtracted from another number, the second number reduces to its 52%; the ratio of the first number to the second number is :
Let the first number be p and second number be q.
⇒ 100q – 60p = 52q⇒ 48q = 60p
∴ | p | = | 48 | = | 4 | or 4 : 5 |
y | 60 | 5 |

.Let the first number be x and
second number be y.
Y - $\frac{60x}{100}$ = $\frac{52Y}{100}$
100y – 60x = 52y
48y = 60x
$\frac{X}{Y}$ =$\frac{48}{60}$= 4:5

Correct Answer:
Description for Correct answer:
Let the first and second number is a and b respectively\( \Large b-\frac{60}{100}a=\frac{52}{100}b \)\( \Large b-\frac{52}{100}b=\frac{60}{100}a \)\( \Large \frac{48}{100}b=\frac{60}{100}a \)\( \Large 4b=5a \)\( \Large \frac{a}{b}=\frac{4}{5} \)
\( \Large \Rightarrow a:b=4:5 \)

When 60% of a number is subtracted from another number, the second number reduces to its 52%; the ratio of the first number to the second number is :
- 6: 5
- 5: 3
- 5: 4
- 4: 5
Correct Option: D
Let the first number be p and second number be q.
∴ q - | 60p | = | 52q | |
100 | 100 |
⇒ 100q – 60p = 52q
⇒ 48q = 60p
∴ | p | = | 48 | = | 4 | or 4 : 5 |
y | 60 | 5 |
