Question 1

Aman gave 30% of his monthly income to his father and of the remaining income he gave 30% to his daughter and 25%
to his wife. Aman invested the amount of money still remaining from his monthly income equally in three schemes. If
he invested 42,000 in each scheme, what is Aman's monthly income (in  thousand)?

अमन अपनी मासिक आय का 30% अपने पिता को और शेष आय का 30% अपनी बेटी को और 25% अपनी पत्नी
को देता है। उसने अपनी मासिक आय में से शेष राशि को तीन योजनाओं में समान रूप से निवेश किया। यदि उसने
प्रत्येक योजना मैं 42,000 का निवेश किया है, तो उसकी मासिक आय ( हजार में) ज्ञात कीजिए।

Solution:

Correct Answer:

C


Aman gave his father = 30%

Aman gave his daughter = 70%×\times 30% = 21%

Aman gave his wife = 70%×\times 25% = 17.5%

Aman’s remaining monthly income = 100 - 30 - 21 - 17.5 = 31.5%

Aman’s invested in every scheme = 31.5%3\frac{31.5%}{3}=10.5%

Now Aman’s monthly income = 42000×10010.5\frac{42000\times 100}{10.5}=400000

Aman's monthly income in thousands = 400

अमन के द्वारा पिता को दी गयी राशि  = 30%

अमन के द्वारा बेटी  को दी गयी राशि = 70%×\times 30% = 21%

अमन के द्वारा पत्नी  को दी गयी राशि = 70%×\times 25% = 17.5%

अमन की बकाया मासिक आय  = 100 - 30 - 21 - 17.5 = 31.5%

अमन के द्वारा प्रत्यक योजना में निवेश   = 31.5%3\frac{31.5%}{3}=10.5%

अब अमन की मासिक आय = 42000×10010.5\frac{42000\times 100}{10.5}=400000

अमन की मासिक आय (हज़ार में) = 400
