Finance ministers of less affluent nations, here for a series of international financial meetings, yesterday adopted a 13-point "laundry list" of demands for help from richer nations, most of which are likely to be rebuffed.

A 14th suggestion, a request for aid in " the promotion and placement of bond issues by developing countries," was dropped out of a final communique.

The various aid demands were put forward by the Group of 24, representing the poor nations of Africa, Asia, and Latin America. Their meeting was preliminary to a two-day session beginning today on the International Monetary Fund's Interim Committee, which represents all 130 IMF nations rich and poor.

Chief among the Group of 24's demands was an increase of 100 per cent in the IMF quotas, in the Seventh General Review of Quotas scheduled to begin next year. A quota determines how much each nation must deposit in its own currency in the IMF, and how much it can borrow, usually in dollars, deutsche marks, or other major currency. A quota also determines a nation's voting also determines a nation's voting power in the IMF.

But it is already a foregone conclusion that a quota increase, to be taken up at the Interim Committee meeting is not likely to be more than 50 per cent, and could be less. The United States is strongly opposed to a quota increase of more than 50 per cent, although the IMF staff has recommended a minimum boost of 75 per cent.

At the conclusion of a meeting of the Group of 10 rich industrial nations, British Chancellor of the Exchecquer Denis Healey said that the interim committee was likely to agree in principle, but not on amounts, for the quota increase and for a special IMF credit to help the poor nations.

Healey yesterday was named chairman of the Group of 10, succeding W. F. Duisenberg of the Netherlands.

At the present time, quotas are undergoing legislative authorization in various countries for the sixth increase in IMF's history, a boost of 32 per cent to roughly the equivalent of $45 billion.

Group of 24 nations also called on the World Bank to agree on a general increase in capital by mid-1978, in order to support more generous loan programs. This is an issue that will be intensely debated in coming months and the Carter administration has given signs that it will view it with an open mind, whereas the Ford administration had flatly opposed it.

It was learned, meanwhile, that the World Bank executive board had adopted $6.8 billion as a "planning assumption" for total loans in fiscal 1979, beginning July 1, 1978. The Washington Post reported on April 7 that the bank, with U.S. acquiescence, had lifted its spending ceiling to $6.1 billion for fiscal 1978, beginning July 1, 1977. This compares with the Ford-enforced ceiling of $5.8 billion for the current fiscal year, ending June 30.

The Group of 24 also gave strong backing to creation of a supplementary credit facility in the IMF to help countries in balance of payments trouble. But while the group called for "low conditionality" - easy terms - sources said yesterday that the Interim Committee would merely approve the idea of a special loan fund, but with "strict conditionality" tough terms.

The Group of 24's ministers warned that less-than-adequate economic expansion in the rich countries would "aggravate the problems of the poor nations. They predicted that the deficits of the non-oil developing countries would be close in 1977 to the $28 billion red ink figure for 1976.
